Quick start guide55.1 ProcedureFollow this procedure:1. Before starting the camera for the first time, charge the battery for 3 hours using thestand-alone battery charger.2. Put the battery into the camera battery compartment.3. Insert a memory card into the card slot.Note Empty or use a memory card that has not previously been used in anothertype of camera. The cameras may organize files differently on the memory card.There is therefore a risk of losing data if the same memory card is used in differenttypes of cameras.4. Push the on/off button to turn on the camera.5. Aim the camera toward the object of interest.6. Adjust the infrared camera focus.Note It is very important to adjust the focus correctly. Incorrect focus adjustment af-fects how the image modes work. It also affects the temperature measurement.7. Push the Save button to save an image.8. Download and install FLIR Tools/Tools+ or FLIR Report Studio on your computer.19. Start FLIR Tools/Tools+ or FLIR Report Studio.10. Connect the camera to the computer using the USB cable.11. Import the images into FLIR Tools/Tools+ or FLIR Report Studio and create an in-spection report.12. Send the inspection report to your client.5.2 To keep in mind• Adjust the focus first. When the camera is out of focus, the measurement will bewrong.• By default, most cameras adapt the scale automatically. Use this mode first, but donot hesitate to set the scale manually.• A thermal camera has a resolution limit. This depends on the size of the detector, thelens, and the distance to the target. Use the center of the spot tool as a guide to theminimum possible object size, and get closer if necessary. Make sure to stay awayfrom dangerous areas and live electrical components.• Be careful when holding the camera perpendicular to the target. Be observant of re-flections, especially at low emissivities—you, the camera, or the surroundings may be-come the main source of reflection.• Select a zone of high emissivity, e.g., an area with a matte surface, to perform ameasurement.• Blank objects, i.e., those with low emissivities, may appear warm or cold in the cam-era, because they mainly reflect the environment.• Avoid direct sunlight on the details that you are inspecting.• Various types of faults, e.g., those in a building’s construction, may result in the sametype of thermal pattern.• Correctly analyzing an infrared image requires professional knowledge about theapplication.#T810253; r.

The laserdistance meter determines the distance to a target by measuring the time it takes for a la-ser pulse to reach the target and return to the laser receiver. This time is converted to adistance, which is displayed on the screen.The laser receiver also works as a laser pointer. When the laser distance meter is on,you will see a laser dot approximately at the target.WARNINGDo not look directly into the laser beam. The laser beam can cause eye irritation.#T810253; r. AA/42549/42549; en-US 19

Camera parts8Note• The laser is enabled by a setting. Select (Settings) > Device settings >Lamp & la-ser >Enable lamp & laser.• The symbol is displayed on the screen when the laser is on.• The camera can be configured to automatically measure the distance when an imageis saved. Select (Settings) > Save options & storage >Measure distance. Withthis setting, the Object distance parameter (see section 16.5 Changing the measure-ment parameters, page 64) in the image data is automatically updated with the meas-ured distance when an image is saved. (There is no effect on the Object distancesetting in live mode.)• If the target reflection is low or if the target is angled from the laser beam, there maybe no return signal, and the distance cannot be measured.• The laser distance meter may not be enabled in all markets.8.4.2 Laser transmitter and receiver1.

Saving and working with images1212.1 About image files12.1.1 GeneralWhen you save an image, the camera saves an image file that includes all thermal andvisual information. This means that you can open an image file at a later time and, for ex-ample, select another image mode, apply color alarms, and add measurement tools.The image *.jpg file is fully radiometric and saved lossless, which enables full post-proc-essing in image analysis and reporting software from FLIR Systems. There is also a reg-ular *.jpg component (lossy) for convenient viewing in non-FLIR Systems software (e.g.,Microsoft Explorer).Note• The camera can also be configured to save an extra low-resolution visual image as aseparate file. This can be convenient if you are not using a post-processing software.Select (Settings) > Save options & storage >Photo as separate JPEG =On.• When the Digital camera image mode is selected, a high-resolution digital image isstored when an image is saved. However, no thermal information is stored. For moreinformation, see section 15 Working with image modes, page 59.12.1.2 File-naming conventionThe default naming convention for image files is FLIRxxxx.jpg, where xxxx is a uniquecounter.It is also possible to save images with a date prefix added to the filename. However,these files may not automatically be detected by third-party applications. For more infor-mation, see the setting File naming format in section 25.1.3 Save options & storage,page 89.12.1.3 Storage capacityWhen you save an image, the camera stores the image file on the memory card.The size of an image file (with no annotations) is typically less than 1000 kB. Thus, thecapacity of a 8 GB memory card is approximately 8000 images.Note Empty or use a memory card that has not previously been used in another type ofcamera. The cameras may organize files differently on the memory card. There is there-fore a risk of losing data if the same memory card is used in different types of cameras.12.1.4 About UltraMaxUltraMax is an image enhancement feature that increases the image resolution and low-ers the noise, making small objects easier to see and measure. An UltraMax image istwice as wide and high as an ordinary image.When an UltraMax image is captured by the camera, several ordinary images are savedwithin the same file. Capturing all the images can take up to 1 second. To fully utilize Ul-traMax, the images need to be slightly different, which can be accomplished by a minutemovement of the camera. You should hold the camera firmly in your hands (do not put iton a tripod), which will make these images vary just a little during the capture. Correct fo-cus, a high-contrast scene, and a non-moving target are other conditions that help toachieve a good-quality UltraMax image.FLIR Tools/Tools+ and FLIR ResearchIR Max have the ability to process UltraMax im-ages. Other FLIR software will treat the image as a regular image.To configure the camera for UltraMax, select (Settings) > Save options & storage >Image resolution =UltraMax.#T810253; r.

Achieving a good image1414.1 GeneralA good image depends on several different functions and settings, although some func-tions and settings affect the image more than others.These are the functions and settings that you need to experiment with:• Adjusting the infrared camera focus.• Adjusting the infrared image (automatically or manually).• Selecting a suitable temperature range.• Selecting a suitable color palette.• Changing the measurement parameters.• Performing a non-uniformity correction (NUC).The following sections explain how to work with these functions and settings.In some situations, you may also want to hide the overlay graphics for a better view.14.2 Adjusting the infrared camera focusIt is very important to adjust the focus correctly. Incorrect focus adjustment affects howthe image modes work. It also affects the temperature measurement.14.2.1 Manual focusYou can adjust the focus manually by rotating the focus ring. For more information, seesection 11.5 Adjusting the infrared camera focus manually, page 29.14.2.2 AutofocusYou can autofocus the infrared camera by pushing the Autofocus button. For more infor-mation, see section 11.6 Autofocusing the infrared camera, page 29.WARNINGWhen the camera is set to autofocusing with the laser method (Settings >Device settings >Focus >Au-to focus >Laser), do not point the camera at the face of a person when you use the autofocus function.The laser beam can cause eye irritation.Note You can also assign the autofocus function to one of the programmable buttons. For more information, see section 11.12 Assigning functions to the programmablebuttons, page 34.14.2.3 Continuous autofocusThe infrared camera can be set up to perform continuous autofocusing. For more infor-mation, see section 11.7 Continuous autofocus, page 30.WARNINGDo not point the camera at the face of a person when the continuous autofocus function is on. The cam-era uses laser distance measurements (that are continuous) for the focus adjustments. The laser beamcan cause eye irritation.14.3 Adjusting the infrared image14.3.1 GeneralAn infrared image can be adjusted automatically or manually.#T810253; r. AA/42549/42549; en-US 51

Achieving a good image14In automatic mode, the camera continuously adjusts the level and span for the best im-age presentation. The colors are distributed based on the thermal content of the image(histogram color distribution). The temperature scale to the right of the screen shows theupper and lower temperatures of the current span.In manual mode, you can adjust the temperature scale to values close to the temperatureof a specific object in the image. This will make it possible to detect anomalies and small-er temperature differences in the part of the image of interest. In manual mode, the col-ors are distributed evenly from the lowest to the highest temperature (linear colordistribution).When manual image adjustment mode is active, an adjustment wheel is displayed to theright of the temperature scale.Figure 14.1 Manual adjustment mode activeIn manual mode, you can adjust the image by touching the screen or by using the naviga-tion pad. For more information, see sections 14.3.2 Manual adjustment by touching thescreen, page 53 and 14.3.3 Manual adjustment by using the navigation pad, page 54.• In live mode, touch the soft button to switch between automatic and manual imageadjustment modes.• In preview/edit mode, manual image adjustment mode is active.Note You can also assign image adjustment functions to the programmable buttons.For more information, see section 11.12 Assigning functions to the programmable but-tons, page 34.•Switch between auto and manual: Allows you to switch between automatic and man-ual image adjustment modes.•Auto adjust the manual temperature scale: Allows you to perform an automatic adjust-ment of the image while remaining in manual image adjustment mode.14.3.1.1 Example 1Here are two infrared images of a building.

If no protective window, protective shield, or external lens isused, this value is irrelevant and should be left inactive.•Object distance, i.e., the distance between the camera and the object of interest.Note The camera can be configured to automatically measure the distance whenan image is saved. With this setting, the Object distance parameter in the image datais automatically updated with the measured distance when an image is saved. (Thereis no effect on the Object distance setting in live mode.) For more information, seesection 8.4 Laser distance meter and laser pointer, page 19.•Atmospheric temperature, i.e., the temperature of the air between the camera and theobject of interest.•Relative humidity, i.e., the relative humidity of the air between the camera and the ob-ject of interest.#T810253; r. AA/42549/42549; en-US 64

Working with measurement tools16•Reflected temperature, which is used when compensating for the radiation from thesurroundings reflected by the object into the camera. This property of the object iscalled “reflectivity.”•Emissivity, i.e., how much radiation an object emits, compared with the radiation of atheoretical reference object at the same temperature (called a “blackbody”). The op-posite of emissivity is reflectivity. The emissivity determines how much of the radiationoriginates from the object as opposed to being reflected by it.Note There is an Emissivity mode setting, which you can use to enter the emissivityby material instead of by value. Select (Settings) > Device settings >User inter-face options >Emissivity mode >Select from materials table.Emissivity is the most important measurement parameter to set correctly. If the Emissivityis set to a low value, the Reflected temperature also becomes important. The parametersObject distance,Atmospheric temperature, and Relative humidity are relevant for longerdistances. The External IR window compensation must be activated if a protective win-dow or external lens is used.16.5.3 Recommended valuesIf you are unsure about the values, the following are recommended:Object distance 1.0 m (3.3 ft.)Atmospheric temperature 20°C (69°F)Relative humidity 50%Reflected temperature 20°C (69°F)Emissivity 0.9516.5.4 ProcedureYou can set the measurement parameters globally. You can also change the Emissivity,Reflected temperature, and Object distance parameters locally for a measurement tool.Local parameters are normally only effective for a fixed setup, where each measurementtool is set for a specific object of interest. For a general handheld application, the globalparameters are usually sufficient.Note Emissivity and Reflected temperature are the two most important measurementparameters to set correctly in the camera.16.5.4.1 Setting global parametersFollow this procedure:1. Push the navigation pad to display the menu system.2. Select (Measurement parameters) and push the navigation pad. This displays asubmenu.3.

Application examples2929.1 Moisture & water damage29.1.1 GeneralIt is often possible to detect moisture and water damage in a house by using an infraredcamera. This is partly because the damaged area has a different heat conduction prop-erty and partly because it has a different thermal capacity to store heat than the sur-rounding material.Many factors can come into play as to how moisture or water damage will appear in aninfrared image.For example, heating and cooling of these parts takes place at different rates dependingon the material and the time of day. For this reason, it is important that other methods areused as well to check for moisture or water damage.29.1.2 FigureThe image below shows extensive water damage on an external wall where the waterhas penetrated the outer facing because of an incorrectly installed window ledge.29.2 Faulty contact in socket29.2.1 GeneralDepending on the type of connection a socket has, an improperly connected wire can re-sult in local temperature increase. This temperature increase is caused by the reducedcontact area between the connection point of the incoming wire and the socket , and canresult in an electrical fire.A socket’s construction may differ dramatically from one manufacturer to another. Forthis reason, different faults in a socket can lead to the same typical appearance in an in-frared image.Local temperature increase can also result from improper contact between wire andsocket, or from difference in load.29.2.2 FigureThe image below shows a connection of a cable to a socket where improper contact inthe connection has resulted in local temperature increase.#T810253; r. AA/42549/42549; en-US 172

Application examples2929.3 Oxidized socket29.3.1 GeneralDepending on the type of socket and the environment in which the socket is installed, ox-ides may occur on the socket's contact surfaces. These oxides can lead to locally in-creased resistance when the socket is loaded, which can be seen in an infrared imageas local temperature increase.A socket’s construction may differ dramatically from one manufacturer to another. Forthis reason, different faults in a socket can lead to the same typical appearance in an in-frared image.Local temperature increase can also result from improper contact between a wire andsocket, or from difference in load.29.3.2 FigureThe image below shows a series of fuses where one fuse has a raised temperature onthe contact surfaces against the fuse holder. Because of the fuse holder’s blank metal,the temperature increase is not visible there, while it is visible on the fuse’s ceramicmaterial.#T810253; r. AA/42549/42549; en-US 173

Application examples2929.4 Insulation deficiencies29.4.1 GeneralInsulation deficiencies may result from insulation losing volume over the course of timeand thereby not entirely filling the cavity in a frame wall.An infrared camera allows you to see these insulation deficiencies because they eitherhave a different heat conduction property than sections with correctly installed insulation,and/or show the area where air is penetrating the frame of the building.When you are inspecting a building, the temperature difference between the inside andoutside should be at least 10°C (18°F). Studs, water pipes, concrete columns, and simi-lar components may resemble an insulation deficiency in an infrared image. Minor differ-ences may also occur naturally.29.4.2 FigureIn the image below, insulation in the roof framing is lacking. Due to the absence of insula-tion, air has forced its way into the roof structure, which thus takes on a different charac-teristic appearance in the infrared image.29.5 Draft29.5.1 GeneralDraft can be found under baseboards, around door and window casings, and above ceil-ing trim. This type of draft is often possible to see with an infrared camera, as a coolerairstream cools down the surrounding surface.When you are investigating draft in a house, there should be sub-atmospheric pressurein the house. Close all doors, windows, and ventilation ducts, and allow the kitchen fanto run for a while before you take the infrared images.An infrared image of draft often shows a typical stream pattern. You can see this streampattern clearly in the picture below.Also keep in mind that drafts can be concealed by heat from floor heating circuits.29.5.2 FigureThe image below shows a ceiling hatch where faulty installation has resulted in a strongdraft.#T810253; r.

Thermographic measurementtechniques3232.1 IntroductionAn infrared camera measures and images the emitted infrared radiation from an object.The fact that radiation is a function of object surface temperature makes it possible forthe camera to calculate and display this temperature.However, the radiation measured by the camera does not only depend on the tempera-ture of the object but is also a function of the emissivity. Radiation also originates fromthe surroundings and is reflected in the object. The radiation from the object and the re-flected radiation will also be influenced by the absorption of the atmosphere.To measure temperature accurately, it is therefore necessary to compensate for the ef-fects of a number of different radiation sources. This is done on-line automatically by thecamera. The following object parameters must, however, be supplied for the camera:• The emissivity of the object• The reflected apparent temperature• The distance between the object and the camera• The relative humidity• Temperature of the atmosphere32.2 EmissivityThe most important object parameter to set correctly is the emissivity which, in short, is ameasure of how much radiation is emitted from the object, compared to that from a per-fect blackbody of the same temperature.Normally, object materials and surface treatments exhibit emissivity ranging from approx-imately 0.1 to 0.95. A highly polished (mirror) surface falls below 0.1, while an oxidizedor painted surface has a higher emissivity. Oil-based paint, regardless of color in the visi-ble spectrum, has an emissivity over 0.9 in the infrared. Human skin exhibits an emissiv-ity 0.97 to 0.98.Non-oxidized metals represent an extreme case of perfect opacity and high reflexivity,which does not vary greatly with wavelength. Consequently, the emissivity of metals islow – only increasing with temperature. For non-metals, emissivity tends to be high, anddecreases with temperature.32.2.1 Finding the emissivity of a sample32.2.1.1 Step 1: Determining reflected apparent temperatureUse one of the following two methods to determine reflected apparent temperature:#T810253; r.

Look for possible reflection sources, considering that the incident angle = reflectionangle (a = b).Figure 32.1 1 = Reflection source2. If the reflection source is a spot source, modify the source by obstructing it using apiece if cardboard.Figure 32.2 1 = Reflection source#T810253; r. AA/42549/42549; en-US 182

Thermographic measurement techniques323. Measure the radiation intensity (= apparent temperature) from the reflection sourceusing the following settings:• Emissivity: 1.0• Dobj: 0You can measure the radiation intensity using one of the following two methods:Figure 32.3 1 = Reflection source Figure 32.4 1 = Reflection sourceYou can not use a thermocouple to measure reflected apparent temperature, because athermocouple measures temperature, but apparent temperatrure is radiation intensity.32.2.1.1.2 Method 2: Reflector methodFollow this procedure:1. Crumble up a large piece of aluminum foil.2. Uncrumble the aluminum foil and attach it to a piece of cardboard of the same size.3. Put the piece of cardboard in front of the object you want to measure. Make sure thatthe side with aluminum foil points to the camera.4. Set the emissivity to 1.0.#T810253; r. AA/42549/42549; en-US 183

Thermographic measurement techniques325. Measure the apparent temperature of the aluminum foil and write it down. The foil isconsidered a perfect reflector, so its apparent temperature equals the reflected appa-rent temperature from the surroundings.Figure 32.5 Measuring the apparent temperature of the aluminum foil.32.2.1.2 Step 2: Determining the emissivityFollow this procedure:1. Select a place to put the sample.2. Determine and set reflected apparent temperature according to the previousprocedure.3. Put a piece of electrical tape with known high emissivity on the sample.4. Heat the sample at least 20 K above room temperature. Heating must be reasonablyeven.5. Focus and auto-adjust the camera, and freeze the image.6. Adjust Level and Span for best image brightness and contrast.7. Set emissivity to that of the tape (usually 0.97).8. Measure the temperature of the tape using one of the following measurementfunctions:•Isotherm (helps you to determine both the temperature and how evenly you haveheated the sample)•Spot (simpler)•Box Avg (good for surfaces with varying emissivity).9. Write down the temperature.10. Move your measurement function to the sample surface.11. Change the emissivity setting until you read the same temperature as your previousmeasurement.12. Write down the emissivity.Note• Avoid forced convection• Look for a thermally stable surrounding that will not generate spot reflections• Use high quality tape that you know is not transparent, and has a high emissivity youare certain of• This method assumes that the temperature of your tape and the sample surface arethe same. If they are not, your emissivity measurement will be wrong.#T810253; r. AA/42549/42549; en-US 184

Thermographic measurement techniques3232.3 Reflected apparent temperatureThis parameter is used to compensate for the radiation reflected in the object. If theemissivity is low and the object temperature relatively far from that of the reflected it willbe important to set and compensate for the reflected apparent temperature correctly.32.4 DistanceThe distance is the distance between the object and the front lens of the camera. Thisparameter is used to compensate for the following two facts:• That radiation from the target is absorbed by the atmosphere between the object andthe camera.• That radiation from the atmosphere itself is detected by the camera.32.5 Relative humidityThe camera can also compensate for the fact that the transmittance is also dependenton the relative humidity of the atmosphere. To do this set the relative humidity to the cor-rect value. For short distances and normal humidity the relative humidity can normally beleft at a default value of 50%.32.6 Other parametersIn addition, some cameras and analysis programs from FLIR Systems allow you to com-pensate for the following parameters:• Atmospheric temperature – i.e. the temperature of the atmosphere between the cam-era and the target• External optics temperature – i.e. the temperature of any external lenses or windowsused in front of the camera• External optics transmittance – i.e. the transmission of any external lenses or windowsused in front of the camera#T810253; r.

The secret to a good thermalimage3333.1 IntroductionThe use of thermal cameras has spread to many professional environments in recentyears. They are easy to handle, and thermal images are quick to take. Images can alsobe attached to reports easily, e.g., for an inspection of an electrical installation or buildingas evidence of work carried out or of any faults or deviations identified. However, peopleoften forget that an image to be used as evidence or even proof before the courts mustmeet certain requirements: this is not achieved with a quick snapshot. So, what charac-terizes a really good thermal image?33.2 BackgroundDuring the practical exercises in our thermography training classes we notice, time andtime again, how difficult some participants find choosing the optimal camera settings fordifferent tasks. Not everyone has a background in, for example, amateur photography(more on the difference between thermography and photography in the next section),and to take a good and meaningful thermal image you need some knowledge of photog-raphy, including its practical application. For this reason, it is hardly surprising that ther-mographers, particularly those without training, repeatedly produce reports with thermalimages that are devoid of meaning or even support the wrong conclusions and are fit on-ly for the waste bin. Unfortunately, such reports are found not only in companies in whichthermography is more of an added bonus but also in businesses where these reportsmay be part of a critical process monitoring or maintenance program. There are two mainreasons for this: either the users don't know what a good thermal image is or how to takeone, or—for whatever reason—the job is not being done properly.33.3 A good imageAs thermography and photography are related, it makes sense to take a look at what isimportant to professional photographers. How do they characterize a good image? Threeaspects can be pointed out as the most important:1. An image has to touch the observer in some way. That means it needs to be unusual,striking, or unique, and has to arouse interest and, depending on the genre, emotion.2. The composition and balance must be in harmony; the image detail and content mustgo together aesthetically.3. The lighting must be interesting, such as back lighting or side lighting that casts dra-matic shadows, or evening light or other pleasing illumination—whatever fits the over-all effect that the photographer wants.To what extent can these concepts be applied to thermography?With thermography, the motif should also be interesting. In other words, our aim is to de-pict an object or its condition. Emotions are not required—facts have priority in thermalimages (assuming they are not an art project!). In everyday working life, it is important toillustrate thermal patterns clearly and to facilitate temperature measurements.The thermal image must also have suitable image detail and display the object at an ap-propriate size and position.Without external illumination, neither visual sight nor photography is possible becausewhat we see with our eyes or capture with a camera is reflected light. In thermography,the camera records both emitted and reflected radiation. Therefore, the relationship andintensity of the infrared radiation, both emitted by the object and by the surrounding envi-ronment, are important. Brightness and contrast in the image are then adjusted bychanging the displayed temperature interval.The comparison between photography and thermography can be summarized in a tableusing a few keywords:Photography ThermographyInteresting motif The object to be examined“Tells a story” “Presents facts”#T810253; r. AA/42549/42549; en-US 186

The secret to a good thermal image33Photography ThermographyAesthetically pleasing Clear heat patternsEmotive ObjectiveImage detail Image detailFocus FocusLighting Emission and reflectionBrightness BrightnessContrast ContrastAs with photography, in thermography there are countless possibilities for editing images—provided they are saved as radiometric images. However, not all settings can bechanged, and not all image errors can be corrected.33.4 The three unchangeables—the basis for a good image33.4.1 FocusA professional thermal image is always focused and sharp, and the object and heat pat-tern must be clear and easy to recognize.Figure 33.1 Only hazy “patches of heat” can be seen in the unfocused image (left). The focused image(right) clearly shows which object is being observed and where the object is warm.A blurred image not only comes across as unprofessional and makes it harder to identifythe object and any faults (see Figure 33.1) but can also lead to measurement errors (seeFigure 33.2), which are more serious the smaller the measurement object. Even if all oth-er parameters are set correctly, the measurement values from an unfocused thermal im-age are highly likely to be incorrect.Figure 33.2 Focused thermal image (left) with a maximum temperature of Tmax = 89.7°C (193.5°F) and anunfocused thermal image (right) with a maximum temperature of Tmax = 73.7°C (164.7°F).Of course, the size of the detector matrix also plays a role in image quality. Images takenby cameras with small detectors (i.e., with fewer pixels) are more blurred or “grainier”and give the impression that they are not focused (see Figure 33.3). It should also benoted that not every camera can be focused, and in this case the only means of focusingthe camera is by changing the distance from the object.#T810253; r. AA/42549/42549; en-US 187

The secret to a good thermal image33Figure 33.3 The same radiator from the same distance with the same settings, taken by three differentthermal cameras: FLIR C2 (left), FLIR T440 (middle), and FLIR T640 (right).33.4.2 Temperature rangeFor hand-held uncooled microbolometer cameras, the “exposure” is essentially preset bythe image frame rate. This means that it is not possible to choose for how long—andtherefore how much—radiation hits the camera detector. For this reason, an appropriatetemperature range must be selected that matches the amount of incident radiation. If atemperature range is selected that is too low, the image will be oversaturated, as objectswith higher temperatures emit more infrared radiation than colder objects. If you select atemperature range that is too high, the thermal image will be “underexposed,” as can beseen in Figure 33.4.Figure 33.4 Images from a FLIR T440 with temperature ranges of –20 to +120°C, (left, –4 to +248°F), 0 to+650°C (middle, +32 to +1202°F) and +250 to +1200°C (right, +482 to +2192°F). All other settings areunchanged.To take an image or temperature measurement, the lowest possible temperature rangeavailable on the camera should be selected. However, it must also include the highesttemperature in the image (see Figure 33.5).Figure 33.5 An image of the same object taken with different temperature ranges: –20 to 120°C (left, –4to +248°F) and 0 to 650°C (right, +32 to +1202°F). The temperature in the left image is displayed with awarning sign (a red circle with a white cross) because the measured values are outside the calibratedrange.Depending on the camera model and configuration options, overdriven and underdrivenareas can be displayed in a contrasting color.33.4.3 Image detail and distance from the objectIllumination in photography corresponds in thermography to the interplay of radiationfrom the object and reflected radiation from the surrounding environment. The latter isunwanted because interfering—or, at the very least, spot—reflections need to beavoided. This is achieved by choosing a suitable position from where to take images. It isalso advisable to select a position from which the object of interest can be seen clearlyand is not hidden. This may seem obvious but in the building sector, for example, it iscommon to find reports in which pipes or windows to be investigated are hidden behind#T810253; r. AA/42549/42549; en-US 188

The secret to a good thermal image33sofas, indoor plants or curtains. Figure 33.6 illustrates this situation—which occurs alltoo regularly.Figure 33.6 “Thermographic inspection” of an inaccessible object.It is also important that the object under investigation, or its areas of interest, take up thewhole thermal image. This is particularly true when measuring the temperature of smallobjects. The spot tool must be completely filled by the object to enable correct tempera-ture measurements. Since the field of view and therefore the spot size are determined byboth the distance to the object and the camera’s optics, in such situations the distance tothe object must either be reduced (get closer!) or a telephoto lens must be used (see Fig-ure 33.7).Figure 33.7 Supply and return lines from radiators in an open-plan office. The left image was taken from adistance of 1 m: the measurement spot is filled and the temperature measurement is correct. The right im-age was taken from a distance of 3 m: the measurement spot is not completely filled and the measuredtemperature values are incorrect (31.4 and 24.4°C (88.5 and 75.9°F) instead of 33.2 and 25.9°C (91.8 and78.6°F)).33.5 The changeables—image optimization and temperature measurement33.5.1 Level and spanAfter choosing the appropriate temperature range, you can adjust the contrast andbrightness of the thermal image by changing the temperature intervals displayed. Inmanual mode, the false colors available in the palette can be assigned to the tempera-tures of the object of interest. This process is often referred to as “thermal tuning.” In au-tomatic mode, the camera selects the coldest and warmest apparent temperatures in theimage as the upper and lower limits of the temperature interval currently displayed.A good or problem-specific scaling of the thermal image is an important step in the inter-pretation of the image, and is, unfortunately, often underestimated (see Figure 33.8).#T810253; r. AA/42549/42549; en-US 189

The secret to a good thermal image33Figure 33.8 A thermal image in automatic mode (left) and in manual model (right). The adjusted tempera-ture interval increases the contrast in the image and makes the faults clear.33.5.2 Palettes and isothermsPalettes represent intervals with the same apparent temperatures using different sets ofcolors. In other words, they translate specific radiation intensities into colors that are spe-cific to a particular palette. Frequently used palettes include the gray, iron, and rainbowpalettes (see Figure 33.9). Gray tones are particularly suited to resolving small geometricdetails but are less suited to displaying small differences in temperature. The iron paletteis very intuitive and also easy to understand for those without much experience in ther-mography. It offers a good balance between geometric and thermal resolution. The rain-bow palette is more colorful and alternates between light and dark colors. This results ingreater contrast, but this can lead to a noisy image for objects with different surfaces ormany temperatures.Figure 33.9 Gray, iron, and rainbow palettes (left to right).The isotherm is a measuring function that displays a given interval of the same apparenttemperature or radiation intensity in a color that is different from the palette. It allows youto emphasize temperature patterns in the image (see Figure 33.10).Figure 33.10 Foundation wall: connection between the old (left in image) and the new (right in image)parts of the building. The isotherm highlights an area of air leakage.33.5.3 Object parametersAs we have seen, the appearance of thermal images is dependent on the thermogra-pher’s technique and choice of settings, and the look of saved radiometric images canbe altered by editing. However, it is also possible to change the settings that are relevantfor the calculation of temperatures. In practice, this means that the emissivity and re-flected apparent temperature can be altered retrospectively. If you notice that these pa-rameters have been set incorrectly or want to add more measurement spots, thetemperature measurement values will be calculated or recalculated according to thechanges (see Figure 33.11).#T810253; r. AA/42549/42549; en-US 190

The secret to a good thermal image33Figure 33.11 Change in emissivity for a saved image. The maximum temperature is 65.0°C (149°F) for ε= 0.95 in the left image and 77.3°C (171.1°F) for ε = 0.7 in the right image.33.6 Taking images—practical tipsThe following list includes some practical tips. However, note that this is not a compre-hensive description of the thermal imaging procedure.• Ensure that the camera is saving radiometric images.• Choose an appropriate position from which to take images:◦ Observe the radiative situation.◦ Check that the object is clearly visible and displayed at an appropriate size andposition.• If you change the emissivity, monitor the temperature range and make sure that it re-mains appropriate.• Focus.• Use a tripod to minimize camera shake.• Carry out thermal tuning.• Take note of the object description, object size, actual distance, environmental condi-tions, and operating conditions.It is easier to edit the thermal image when it is saved or “frozen” (in “Preview”). Also,since you don't have to do everything on site, you can leave dangerous zones immedi-ately after taking the image. If possible, take a few more images than you need—includ-ing from different angles. This is preferable to taking too few! You can then choose thebest image afterwards, at leisure.33.7 ConclusionTaking a good thermal image does not require any magic tricks—solid craft and soundwork is all that is required. Many of the points mentioned may seem trivial and “old news,”particularly to amateur photographers. Of course, the equipment plays a role easier toensure sharp images. Better, i.e. high-definition, cameras allow the fast localization ofeven small anomalies, and without focusing capabilities it is always difficult to capture asharp image. However, high-end cameras are no guarantee of good images if used in-correctly. The basis for good, professional work is education and training in thermogra-phy, exchange of knowledge with other thermographers, and, of course, practicalexperience.#T810253; r.

About calibration3434.1 IntroductionCalibration of a thermal camera is a prerequisite for temperature measurement. The cali-bration provides the relationship between the input signal and the physical quantity thatthe user wants to measure. However, despite its widespread and frequent use, the term“calibration” is often misunderstood and misused. Local and national differences as wellas translation-related issues create additional confusion.Unclear terminology can lead to difficulties in communication and erroneous translations,and subsequently to incorrect measurements due to misunderstandings and, in the worstcase, even to lawsuits.34.2 Definition—what is calibration?The International Bureau of Weights and Measures16 defines calibration17 in the followingway:an operation that, under specified conditions, in a first step, establishes a relation be-tween the quantity values with measurement uncertainties provided by measurementstandards and corresponding indications with associated measurement uncertaintiesand, in a second step, uses this information to establish a relation for obtaining a meas-urement result from an indication.The calibration itself may be expressed in different formats: this can be a statement, cali-bration function, calibration diagram18, calibration curve19, or calibration table.Often, the first step alone in the above definition is perceived and referred to as being“calibration.” However, this is not (always) sufficient.Considering the calibration procedure of a thermal camera, the first step establishes therelation between emitted radiation (the quantity value) and the electrical output signal(the indication). This first step of the calibration procedure consists of obtaining a homo-geneous (or uniform) response when the camera is placed in front of an extended sourceof radiation.As we know the temperature of the reference source emitting the radiation, in the secondstep the obtained output signal (the indication) can be related to the reference source’stemperature (measurement result). The second step includes drift measurement andcompensation.To be correct, calibration of a thermal camera is, strictly, not expressed through tempera-ture. Thermal cameras are sensitive to infrared radiation: therefore, at first you obtain aradiance correspondence, then a relationship between radiance and temperature. Forbolometer cameras used by non-R&D customers, radiance is not expressed: only thetemperature is provided.34.3 Camera calibration at FLIR SystemsWithout calibration, an infrared camera would not be able to measure either radiance ortemperature. At FLIR Systems, the calibration of uncooled microbolometer cameras witha measurement capability is carried out during both production and service. Cooled cam-eras with photon detectors are often calibrated by the user with special software. Withthis type of software, in theory, common handheld uncooled thermal cameras could becalibrated by the user too. However, as this software is not suitable for reporting#T810253; r.

About calibration34purposes, most users do not have it. Non-measuring devices that are used for imagingonly do not need temperature calibration. Sometimes this is also reflected in camera ter-minology when talking about infrared or thermal imaging cameras compared with ther-mography cameras, where the latter are the measuring devices.The calibration information, no matter if the calibration is done by FLIR Systems or theuser, is stored in calibration curves, which are expressed by mathematical functions. Asradiation intensity changes with both temperature and the distance between the objectand the camera, different curves are generated for different temperature ranges and ex-changeable lenses.34.4 The differences between a calibrationperformed by a user and that performed directlyat FLIR SystemsFirst, the reference sources that FLIR Systems uses are themselves calibrated andtraceable. This means, at each FLIR Systems site performing calibration, that the sour-ces are controlled by an independent national authority. The camera calibration certifi-cate is confirmation of this. It is proof that not only has the calibration been performed byFLIR Systems but that it has also been carried out using calibrated references. Someusers own or have access to accredited reference sources, but they are very few innumber.Second, there is a technical difference. When performing a user calibration, the result isoften (but not always) not drift compensated. This means that the values do not take intoaccount a possible change in the camera’s output when the camera’s internal tempera-ture varies. This yields a larger uncertainty. Drift compensation uses data obtained in cli-mate-controlled chambers. All FLIR Systems cameras are drift compensated when theyare first delivered to the customer and when they are recalibrated by FLIR Systems serv-ice departments.34.5 Calibration, verification and adjustmentA common misconception is to confuse calibration with verification or adjustment. In-deed, calibration is a prerequisite for verification, which provides confirmation that speci-fied requirements are met. Verification provides objective evidence that a given itemfulfills specified requirements. To obtain the verification, defined temperatures (emittedradiation) of calibrated and traceable reference sources are measured. The measure-ment results, including the deviation, are noted in a table. The verification certificatestates that these measurement results meet specified requirements. Sometimes, compa-nies or organizations offer and market this verification certificate as a “calibrationcertificate.”Proper verification—and by extension calibration and/or recalibration—can only beachieved when a validated protocol is respected. The process is more than placing thecamera in front of blackbodies and checking if the camera output (as temperature, for in-stance) corresponds to the original calibration table. It is often forgotten that a camera isnot sensitive to temperature but to radiation. Furthermore, a camera is an imaging sys-tem, not just a single sensor. Consequently, if the optical configuration allowing the cam-era to “collect” radiance is poor or misaligned, then the “verification” (or calibration orrecalibration) is worthless.For instance, one has to ensure that the distance between the blackbody and the cameraas well as the diameter of the blackbody cavity are chosen so as to reduce stray radiationand the size-of-source effect.To summarize: a validated protocol must comply with the physical laws for radiance, andnot only those for temperature.#T810253; r. AA/42549/42549; en-US 193

About calibration34Calibration is also a prerequisite for adjustment, which is the set of operations carried outon a measuring system such that the system provides prescribed indications corre-sponding to given values of quantities to be measured, typically obtained from measure-ment standards. Simplified, adjustment is a manipulation that results in instruments thatmeasure correctly within their specifications. In everyday language, the term “calibration”is widely used instead of “adjustment” for measuring devices.34.6 Non-uniformity correctionWhen the thermal camera displays ”Calibrating…” it is adjusting for the deviation in re-sponse of each individual detector element (pixel). In thermography, this is called a ”non-uniformity correction” (NUC). It is an offset update, and the gain remains unchanged.The European standard EN 16714-3, Non-destructive Testing—Thermographic Testing—Part 3: Terms and Definitions, defines an NUC as “Image correction carried out by thecamera software to compensate for different sensitivities of detector elements and otheroptical and geometrical disturbances.”During the NUC (the offset update), a shutter (internal flag) is placed in the optical path,and all the detector elements are exposed to the same amount of radiation originatingfrom the shutter. Therefore, in an ideal situation, they should all give the same output sig-nal. However, each individual element has its own response, so the output is not uniform.This deviation from the ideal result is calculated and used to mathematically perform animage correction, which is essentially a correction of the displayed radiation signal.Some cameras do not have an internal flag. In this case, the offset update must be per-formed manually using special software and an external uniform source of radiation.An NUC is performed, for example, at start-up, when changing a measurement range, orwhen the environment temperature changes. Some cameras also allow the user to trig-ger it manually. This is useful when you have to perform a critical measurement with aslittle image disturbance as possible.34.7 Thermal image adjustment (thermaltuning)Some people use the term “image calibration” when adjusting the thermal contrast andbrightness in the image to enhance specific details. During this operation, the tempera-ture interval is set in such a way that all available colors are used to show only (or mainly)the temperatures in the region of interest. The correct term for this manipulation is “ther-mal image adjustment” or “thermal tuning”, or, in some languages, “thermal image optimi-zation.” You must be in manual mode to undertake this, otherwise the camera will set thelower and upper limits of the displayed temperature interval automatically to the coldestand hottest temperatures in the scene.#T810253; r.

History of infrared technology35Before the year 1800, the existence of the infrared portion of the electromagnetic spec-trum wasn't even suspected. The original significance of the infrared spectrum, or simply‘the infrared’ as it is often called, as a form of heat radiation is perhaps less obvious to-day than it was at the time of its discovery by Herschel in 1800.Figure 35.1 Sir William Herschel (1738–1822)The discovery was made accidentally during the search for a new optical material. SirWilliam Herschel – Royal Astronomer to King George III of England, and already famousfor his discovery of the planet Uranus – was searching for an optical filter material to re-duce the brightness of the sun’s image in telescopes during solar observations. Whiletesting different samples of colored glass which gave similar reductions in brightness hewas intrigued to find that some of the samples passed very little of the sun’s heat, whileothers passed so much heat that he risked eye damage after only a few seconds’observation.Herschel was soon convinced of the necessity of setting up a systematic experiment,with the objective of finding a single material that would give the desired reduction inbrightness as well as the maximum reduction in heat. He began the experiment by ac-tually repeating Newton’s prism experiment, but looking for the heating effect rather thanthe visual distribution of intensity in the spectrum. He first blackened the bulb of a sensi-tive mercury-in-glass thermometer with ink, and with this as his radiation detector he pro-ceeded to test the heating effect of the various colors of the spectrum formed on the topof a table by passing sunlight through a glass prism. Other thermometers, placed outsidethe sun’s rays, served as controls.As the blackened thermometer was moved slowly along the colors of the spectrum, thetemperature readings showed a steady increase from the violet end to the red end. Thiswas not entirely unexpected, since the Italian researcher, Landriani, in a similar experi-ment in 1777 had observed much the same effect. It was Herschel, however, who wasthe first to recognize that there must be a point where the heating effect reaches a maxi-mum, and that measurements confined to the visible portion of the spectrum failed to lo-cate this point.Figure 35.2 Marsilio Landriani (1746–1815)Moving the thermometer into the dark region beyond the red end of the spectrum, Her-schel confirmed that the heating continued to increase. The maximum point, when hefound it, lay well beyond the red end – in what is known today as the ‘infraredwavelengths’.#T810253; r. AA/42549/42549; en-US 195

History of infrared technology35When Herschel revealed his discovery, he referred to this new portion of the electromag-netic spectrum as the ‘thermometrical spectrum’. The radiation itself he sometimes re-ferred to as ‘dark heat’, or simply ‘the invisible rays’. Ironically, and contrary to popularopinion, it wasn't Herschel who originated the term ‘infrared’. The word only began to ap-pear in print around 75 years later, and it is still unclear who should receive credit as theoriginator.Herschel’s use of glass in the prism of his original experiment led to some early contro-versies with his contemporaries about the actual existence of the infrared wavelengths.Different investigators, in attempting to confirm his work, used various types of glass in-discriminately, having different transparencies in the infrared. Through his later experi-ments, Herschel was aware of the limited transparency of glass to the newly-discoveredthermal radiation, and he was forced to conclude that optics for the infrared would prob-ably be doomed to the use of reflective elements exclusively (i.e. plane and curved mir-rors). Fortunately, this proved to be true only until 1830, when the Italian investigator,Melloni, made his great discovery that naturally occurring rock salt (NaCl) – which wasavailable in large enough natural crystals to be made into lenses and prisms – is remark-ably transparent to the infrared. The result was that rock salt became the principal infra-red optical material, and remained so for the next hundred years, until the art of syntheticcrystal growing was mastered in the 1930’s.Figure 35.3 Macedonio Melloni (1798–1854)Thermometers, as radiation detectors, remained unchallenged until 1829, the year Nobiliinvented the thermocouple. (Herschel’s own thermometer could be read to 0.2 °C(0.036 °F), and later models were able to be read to 0.05 °C (0.09 °F)). Then a break-through occurred; Melloni connected a number of thermocouples in series to form thefirst thermopile. The new device was at least 40 times as sensitive as the best thermome-ter of the day for detecting heat radiation – capable of detecting the heat from a personstanding three meters away.The first so-called ‘heat-picture’ became possible in 1840, the result of work by Sir JohnHerschel, son of the discoverer of the infrared and a famous astronomer in his own right.Based upon the differential evaporation of a thin film of oil when exposed to a heat pat-tern focused upon it, the thermal image could be seen by reflected light where the inter-ference effects of the oil film made the image visible to the eye. Sir John also managedto obtain a primitive record of the thermal image on paper, which he called a‘thermograph’.#T810253; r. AA/42549/42549; en-US 196

History of infrared technology35Figure 35.4 Samuel P. Langley (1834–1906)The improvement of infrared-detector sensitivity progressed slowly. Another major break-through, made by Langley in 1880, was the invention of the bolometer. This consisted ofa thin blackened strip of platinum connected in one arm of a Wheatstone bridge circuitupon which the infrared radiation was focused and to which a sensitive galvanometer re-sponded. This instrument is said to have been able to detect the heat from a cow at adistance of 400 meters.An English scientist, Sir James Dewar, first introduced the use of liquefied gases as cool-ing agents (such as liquid nitrogen with a temperature of –196°C (–320.8°F)) in low tem-perature research. In 1892 he invented a unique vacuum insulating container in which itis possible to store liquefied gases for entire days. The common ‘thermos bottle’, usedfor storing hot and cold drinks, is based upon his invention.Between the years 1900 and 1920, the inventors of the world ‘discovered’ the infrared.Many patents were issued for devices to detect personnel, artillery, aircraft, ships – andeven icebergs. The first operating systems, in the modern sense, began to be developedduring the 1914–18 war, when both sides had research programs devoted to the militaryexploitation of the infrared. These programs included experimental systems for enemyintrusion/detection, remote temperature sensing, secure communications, and ‘flying tor-pedo’ guidance. An infrared search system tested during this period was able to detectan approaching airplane at a distance of 1.5 km (0.94 miles), or a person more than 300meters (984 ft.) away.The most sensitive systems up to this time were all based upon variations of the bolome-ter idea, but the period between the two wars saw the development of two revolutionarynew infrared detectors: the image converter and the photon detector. At first, the imageconverter received the greatest attention by the military, because it enabled an observerfor the first time in history to literally ‘see in the dark’. However, the sensitivity of the im-age converter was limited to the near infrared wavelengths, and the most interesting mili-tary targets (i.e. enemy soldiers) had to be illuminated by infrared search beams. Sincethis involved the risk of giving away the observer’s position to a similarly-equipped enemyobserver, it is understandable that military interest in the image converter eventuallyfaded.The tactical military disadvantages of so-called 'active’ (i.e. search beam-equipped) ther-mal imaging systems provided impetus following the 1939–45 war for extensive secretmilitary infrared-research programs into the possibilities of developing ‘passive’ (nosearch beam) systems around the extremely sensitive photon detector. During this peri-od, military secrecy regulations completely prevented disclosure of the status of infrared-imaging technology. This secrecy only began to be lifted in the middle of the 1950’s, andfrom that time adequate thermal-imaging devices finally began to be available to civilianscience and industry.#T810253; r.

Theory of thermography3636.1 IntroductionThe subjects of infrared radiation and the related technique of thermography are still newto many who will use an infrared camera. In this section the theory behind thermographywill be given.36.2 The electromagnetic spectrumThe electromagnetic spectrum is divided arbitrarily into a number of wavelength regions,called bands, distinguished by the methods used to produce and detect the radiation.There is no fundamental difference between radiation in the different bands of the elec-tromagnetic spectrum. They are all governed by the same laws and the only differencesare those due to differences in wavelength.Figure 36.1 The electromagnetic spectrum. 1: X-ray; 2: UV; 3: Visible; 4: IR; 5: Microwaves; 6:Radiowaves.Thermography makes use of the infrared spectral band. At the short-wavelength end theboundary lies at the limit of visual perception, in the deep red. At the long-wavelengthend it merges with the microwave radio wavelengths, in the millimeter range.The infrared band is often further subdivided into four smaller bands, the boundaries ofwhich are also arbitrarily chosen. They include: the near infrared (0.75–3 μm), the middleinfrared (3–6 μm), the far infrared (6–15 μm) and the extreme infrared (15–100 μm).Although the wavelengths are given in μm (micrometers), other units are often still usedto measure wavelength in this spectral region, e.g. nanometer (nm) and Ångström (Å).The relationships between the different wavelength measurements is:36.3 Blackbody radiationA blackbody is defined as an object which absorbs all radiation that impinges on it at anywavelength. The apparent misnomer black relating to an object emitting radiation is ex-plained by Kirchhoff’s Law (after Gustav Robert Kirchhoff, 1824–1887), which states thata body capable of absorbing all radiation at any wavelength is equally capable in theemission of radiation.#T810253; r. AA/42549/42549; en-US 198

$Theory of thermography36Figure 36.2 Gustav Robert Kirchhoff (1824–1887)The construction of a blackbody source is, in principle, very simple. The radiation charac-teristics of an aperture in an isotherm cavity made of an opaque absorbing material rep-resents almost exactly the properties of a blackbody. A practical application of theprinciple to the construction of a perfect absorber of radiation consists of a box that islight tight except for an aperture in one of the sides. Any radiation which then enters thehole is scattered and absorbed by repeated reflections so only an infinitesimal fractioncan possibly escape. The blackness which is obtained at the aperture is nearly equal toa blackbody and almost perfect for all wavelengths.By providing such an isothermal cavity with a suitable heater it becomes what is termedacavity radiator. An isothermal cavity heated to a uniform temperature generates black-body radiation, the characteristics of which are determined solely by the temperature ofthe cavity. Such cavity radiators are commonly used as sources of radiation in tempera-ture reference standards in the laboratory for calibrating thermographic instruments,such as a FLIR Systems camera for example.If the temperature of blackbody radiation increases to more than 525°C (977°F), thesource begins to be visible so that it appears to the eye no longer black. This is the incipi-ent red heat temperature of the radiator, which then becomes orange or yellow as thetemperature increases further. In fact, the definition of the so-called color temperature ofan object is the temperature to which a blackbody would have to be heated to have thesame appearance.Now consider three expressions that describe the radiation emitted from a blackbody.36.3.1 Planck’s lawFigure 36.3 Max Planck (1858–1947)Max Planck (1858–1947) was able to describe the spectral distribution of the radiationfrom a blackbody by means of the following formula:#T810253; r. AA/42549/42549; en-US 199$

Theory of thermography36where:Wλb Blackbody spectral radiant emittance at wavelength λ.cVelocity of light = 3 × 108m/sh Planck’s constant = 6.6 × 10-34 Joule sec.kBoltzmann’s constant = 1.4 × 10-23 Joule/K.T Absolute temperature (K) of a blackbody.λ Wavelength (μm).Note The factor 10-6 is used since spectral emittance in the curves is expressed inWatt/m2, μm.Planck’s formula, when plotted graphically for various temperatures, produces a family ofcurves. Following any particular Planck curve, the spectral emittance is zero at λ = 0,then increases rapidly to a maximum at a wavelength λmax and after passing it ap-proaches zero again at very long wavelengths. The higher the temperature, the shorterthe wavelength at which maximum occurs.Figure 36.4 Blackbody spectral radiant emittance according to Planck’s law, plotted for various absolutetemperatures. 1: Spectral radiant emittance (W/cm2× 103(μm)); 2: Wavelength (μm)36.3.2 Wien’s displacement lawBy differentiating Planck’s formula with respect to λ, and finding the maximum, we have:This is Wien’s formula (after Wilhelm Wien, 1864–1928), which expresses mathemati-cally the common observation that colors vary from red to orange or yellow as the tem-perature of a thermal radiator increases. The wavelength of the color is the same as thewavelength calculated for λmax. A good approximation of the value of λmax for a givenblackbody temperature is obtained by applying the rule-of-thumb 3 000/T μm. Thus, avery hot star such as Sirius (11 000 K), emitting bluish-white light, radiates with the peakof spectral radiant emittance occurring within the invisible ultraviolet spectrum, at wave-length 0.27 μm.#T810253; r. AA/42549/42549; en-US 200

Theory of thermography36Figure 36.5 Wilhelm Wien (1864–1928)The sun (approx. 6 000 K) emits yellow light, peaking at about 0.5 μm in the middle ofthe visible light spectrum.At room temperature (300 K) the peak of radiant emittance lies at 9.7 μm, in the far infra-red, while at the temperature of liquid nitrogen (77 K) the maximum of the almost insignif-icant amount of radiant emittance occurs at 38 μm, in the extreme infrared wavelengths.Figure 36.6 Planckian curves plotted on semi-log scales from 100 K to 1000 K. The dotted line representsthe locus of maximum radiant emittance at each temperature as described by Wien's displacement law. 1:Spectral radiant emittance (W/cm2(μm)); 2: Wavelength (μm).36.3.3 Stefan-Boltzmann's lawBy integrating Planck’s formula from λ = 0 to λ = ∞, we obtain the total radiant emittance(Wb) of a blackbody:This is the Stefan-Boltzmann formula (after Josef Stefan, 1835–1893, and Ludwig Boltz-mann, 1844–1906), which states that the total emissive power of a blackbody is propor-tional to the fourth power of its absolute temperature. Graphically, Wbrepresents thearea below the Planck curve for a particular temperature. It can be shown that the radiantemittance in the interval λ = 0 to λmax is only 25% of the total, which represents about theamount of the sun’s radiation which lies inside the visible light spectrum.#T810253; r. AA/42549/42549; en-US 201

$Theory of thermography36Figure 36.7 Josef Stefan (1835–1893), and Ludwig Boltzmann (1844–1906)Using the Stefan-Boltzmann formula to calculate the power radiated by the human body,at a temperature of 300 K and an external surface area of approx. 2 m2, we obtain 1 kW.This power loss could not be sustained if it were not for the compensating absorption ofradiation from surrounding surfaces, at room temperatures which do not vary too drasti-cally from the temperature of the body – or, of course, the addition of clothing.36.3.4 Non-blackbody emittersSo far, only blackbody radiators and blackbody radiation have been discussed. However,real objects almost never comply with these laws over an extended wavelength region –although they may approach the blackbody behavior in certain spectral intervals. For ex-ample, a certain type of white paint may appear perfectly white in the visible light spec-trum, but becomes distinctly gray at about 2 μm, and beyond 3 μm it is almost black.There are three processes which can occur that prevent a real object from acting like ablackbody: a fraction of the incident radiation α may be absorbed, a fraction ρ may be re-flected, and a fraction τ may be transmitted. Since all of these factors are more or lesswavelength dependent, the subscript λ is used to imply the spectral dependence of theirdefinitions. Thus:• The spectral absorptance αλ= the ratio of the spectral radiant power absorbed by anobject to that incident upon it.• The spectral reflectance ρλ= the ratio of the spectral radiant power reflected by an ob-ject to that incident upon it.• The spectral transmittance τλ= the ratio of the spectral radiant power transmittedthrough an object to that incident upon it.The sum of these three factors must always add up to the whole at any wavelength, sowe have the relation:For opaque materials τλ= 0 and the relation simplifies to:Another factor, called the emissivity, is required to describe the fraction ε of the radiantemittance of a blackbody produced by an object at a specific temperature. Thus, wehave the definition:The spectral emissivity ελ= the ratio of the spectral radiant power from an object to thatfrom a blackbody at the same temperature and wavelength.Expressed mathematically, this can be written as the ratio of the spectral emittance ofthe object to that of a blackbody as follows:Generally speaking, there are three types of radiation source, distinguished by the waysin which the spectral emittance of each varies with wavelength.• A blackbody, for which ελ= ε = 1• A graybody, for which ελ= ε = constant less than 1#T810253; r. AA/42549/42549; en-US 202$

Theory of thermography36• A selective radiator, for which ε varies with wavelengthAccording to Kirchhoff’s law, for any material the spectral emissivity and spectral absorp-tance of a body are equal at any specified temperature and wavelength. That is:From this we obtain, for an opaque material (since αλ+ ρλ= 1):For highly polished materials ελapproaches zero, so that for a perfectly reflecting materi-al (i.e. a perfect mirror) we have:For a graybody radiator, the Stefan-Boltzmann formula becomes:This states that the total emissive power of a graybody is the same as a blackbody at thesame temperature reduced in proportion to the value of ε from the graybody.Figure 36.8 Spectral radiant emittance of three types of radiators. 1: Spectral radiant emittance; 2: Wave-length; 3: Blackbody; 4: Selective radiator; 5: Graybody.Figure 36.9 Spectral emissivity of three types of radiators. 1: Spectral emissivity; 2: Wavelength; 3: Black-body; 4: Graybody; 5: Selective radiator.#T810253; r. AA/42549/42549; en-US 203

Theory of thermography3636.4 Infrared semi-transparent materialsConsider now a non-metallic, semi-transparent body – let us say, in the form of a thick flatplate of plastic material. When the plate is heated, radiation generated within its volumemust work its way toward the surfaces through the material in which it is partially ab-sorbed. Moreover, when it arrives at the surface, some of it is reflected back into the inte-rior. The back-reflected radiation is again partially absorbed, but some of it arrives at theother surface, through which most of it escapes; part of it is reflected back again.Although the progressive reflections become weaker and weaker they must all be addedup when the total emittance of the plate is sought. When the resulting geometrical seriesis summed, the effective emissivity of a semi-transparent plate is obtained as:When the plate becomes opaque this formula is reduced to the single formula:This last relation is a particularly convenient one, because it is often easier to measurereflectance than to measure emissivity directly.#T810253; r. AA/42549/42549; en-US 204

The measurement formula37As already mentioned, when viewing an object, the camera receives radiation not onlyfrom the object itself. It also collects radiation from the surroundings reflected via the ob-ject surface. Both these radiation contributions become attenuated to some extent by theatmosphere in the measurement path. To this comes a third radiation contribution fromthe atmosphere itself.This description of the measurement situation, as illustrated in the figure below, is so fara fairly true description of the real conditions. What has been neglected could for in-stance be sun light scattering in the atmosphere or stray radiation from intense radiationsources outside the field of view. Such disturbances are difficult to quantify, however, inmost cases they are fortunately small enough to be neglected. In case they are not negli-gible, the measurement configuration is likely to be such that the risk for disturbance isobvious, at least to a trained operator. It is then his responsibility to modify the measure-ment situation to avoid the disturbance e.g. by changing the viewing direction, shieldingoff intense radiation sources etc.Accepting the description above, we can use the figure below to derive a formula for thecalculation of the object temperature from the calibrated camera output.Figure 37.1 A schematic representation of the general thermographic measurement situation.1: Sur-roundings; 2: Object; 3: Atmosphere; 4: CameraAssume that the received radiation power W from a blackbody source of temperatureTsource on short distance generates a camera output signal Usource that is proportional tothe power input (power linear camera). We can then write (Equation 1):or, with simplified notation:where C is a constant.Should the source be a graybody with emittance ε, the received radiation would conse-quently be εWsource.We are now ready to write the three collected radiation power terms:1. Emission from the object = ετWobj, where ε is the emittance of the object and τ is thetransmittance of the atmosphere. The object temperature is Tobj.#T810253; r. AA/42549/42549; en-US 205

The measurement formula372. Reflected emission from ambient sources = (1 – ε)τWrefl, where (1 – ε) is the reflec-tance of the object. The ambient sources have the temperature Trefl.It has here been assumed that the temperature Trefl is the same for all emitting surfa-ces within the halfsphere seen from a point on the object surface. This is of coursesometimes a simplification of the true situation. It is, however, a necessary simplifica-tion in order to derive a workable formula, and Trefl can – at least theoretically – be giv-en a value that represents an efficient temperature of a complex surrounding.Note also that we have assumed that the emittance for the surroundings = 1. This iscorrect in accordance with Kirchhoff’s law: All radiation impinging on the surroundingsurfaces will eventually be absorbed by the same surfaces. Thus the emittance = 1.(Note though that the latest discussion requires the complete sphere around the ob-ject to be considered.)3. Emission from the atmosphere = (1 – τ)τWatm, where (1 – τ) is the emittance of the at-mosphere. The temperature of the atmosphere is Tatm.The total received radiation power can now be written (Equation 2):We multiply each term by the constant C of Equation 1 and replace the CW products bythe corresponding U according to the same equation, and get (Equation 3):Solve Equation 3 for Uobj (Equation 4):This is the general measurement formula used in all the FLIR Systems thermographicequipment. The voltages of the formula are:Table 37.1 VoltagesUobj Calculated camera output voltage for a blackbody of temperatureTobj i.e. a voltage that can be directly converted into true requestedobject temperature.Utot Measured camera output voltage for the actual case.Urefl Theoretical camera output voltage for a blackbody of temperatureTrefl according to the calibration.Uatm Theoretical camera output voltage for a blackbody of temperatureTatm according to the calibration.The operator has to supply a number of parameter values for the calculation:• the object emittance ε,• the relative humidity,• Tatm• object distance (Dobj)• the (effective) temperature of the object surroundings, or the reflected ambient tem-perature Trefl, and• the temperature of the atmosphere TatmThis task could sometimes be a heavy burden for the operator since there are normallyno easy ways to find accurate values of emittance and atmospheric transmittance for theactual case. The two temperatures are normally less of a problem provided the surround-ings do not contain large and intense radiation sources.A natural question in this connection is: How important is it to know the right values ofthese parameters? It could though be of interest to get a feeling for this problem alreadyhere by looking into some different measurement cases and compare the relative#T810253; r. AA/42549/42549; en-US 206

The measurement formula37magnitudes of the three radiation terms. This will give indications about when it is impor-tant to use correct values of which parameters.The figures below illustrates the relative magnitudes of the three radiation contributionsfor three different object temperatures, two emittances, and two spectral ranges: SW andLW. Remaining parameters have the following fixed values:• τ = 0.88• Trefl = +20°C (+68°F)• Tatm = +20°C (+68°F)It is obvious that measurement of low object temperatures are more critical than measur-ing high temperatures since the ‘disturbing’ radiation sources are relatively much stron-ger in the first case. Should also the object emittance be low, the situation would be stillmore difficult.We have finally to answer a question about the importance of being allowed to use thecalibration curve above the highest calibration point, what we call extrapolation. Imaginethat we in a certain case measure Utot = 4.5 volts. The highest calibration point for thecamera was in the order of 4.1 volts, a value unknown to the operator. Thus, even if theobject happened to be a blackbody, i.e. Uobj = Utot, we are actually performing extrapola-tion of the calibration curve when converting 4.5 volts into temperature.Let us now assume that the object is not black, it has an emittance of 0.75, and the trans-mittance is 0.92. We also assume that the two second terms of Equation 4 amount to 0.5volts together. Computation of Uobj by means of Equation 4 then results in Uobj = 4.5 /0.75 / 0.92 – 0.5 = 6.0. This is a rather extreme extrapolation, particularly when consider-ing that the video amplifier might limit the output to 5 volts! Note, though, that the applica-tion of the calibration curve is a theoretical procedure where no electronic or otherlimitations exist. We trust that if there had been no signal limitations in the camera, and ifit had been calibrated far beyond 5 volts, the resulting curve would have been very muchthe same as our real curve extrapolated beyond 4.1 volts, provided the calibration algo-rithm is based on radiation physics, like the FLIR Systems algorithm. Of course theremust be a limit to such extrapolations.Figure 37.2 Relative magnitudes of radiation sources under varying measurement conditions (SW cam-era). 1: Object temperature; 2: Emittance; Obj: Object radiation; Refl: Reflected radiation; Atm: atmos-phere radiation.
