50 4.7.1. Relative permittivity and depth calibration The relative permittivity is an object-specific coefficient showing the relationship between the electromagnetic propagation speed in the air and scanned medium. This product measures the time between the time of transmitting the signal and the time receiving the signal reflected at the embedded object, then calculates the depth of the embedded object by using the measured time and electromagnetic propagation speed determined by the relative permittivity of the scanned medium Depending upon the relative permittivity entered, this product can correct the depth scale on the scan screen. Therefore setting the appropriate value to the relative permittivity is the key factor to get the accurate depth of the detected object. For the theory of operation, refer to 8 Theory. Depth calibration is performed by estimating the relative permittivity of the scanned concrete and setting the value to the relative permitivity. When the relative permittivity of the scanned concrete is known, enter the known value to the relative permittivity. For the setting procedure, refer to Sections 4.7 [Relative permittivity] icon and 4.11.1 Device setting: [Relative permittivity] menu. To reduce depth error when the relative permittivity of the scanned concrete is unknown, perform the depth calibration before the scanning with the following procedure. (1) Scan the object whose actual depth is known (Ex. the rebar with a known depth or a wall with the known width) and detect the depth of the object. (2) Adjust the relative permittivity value so that the depth displayed in the scan result matches with the known depth. When the object with a known depth is not avaialble and the relative dielectric constant of the concrete is unclear, it is recommended to set 8.0 (+0) as the relative permittivity. y The relative permittivity depends on the condition (such as moisture content) of the concrete being scanned. Therefore the more difference between the actual relative dielectric constant of the concrete and the entered value, the more the depth error. Set an appropriate value to this parameter to get the accurate depth. Note
51 4.8. [View range] icon [View range] icon allows you to change the view range for the scan result displayed at the idle state. (The setting made by this icon is valid only for the scan result image displayed at the idle state. After starting a new scan, the setting for the measurement is restored to the original device setting. For the setting as the devie setting, refer to Section 4.11.3 Device setting: [View range] menu.) The view range specifies the displayed range of depth and distance in B mode screen. Select the adequate range matched with the depth of the scan target as follows. The available settings are Shallow, Normal, Deep, Shallow Wide, Normal Wide, and Deep Wide.

53 4.9.1. Sensitivity The first letter A of the setting name AS indicates the overall sensitivity, and the second letter S (Shallow) indicates the sensitivity by the depth. The overall sensitivity consists of five levels: -2 , -1 , A , +1 , +2 . The A setting is the middle of all overall sensitivity settings and is used normally. Use the +side (+1 and +2) to increase the sensitivity and the –side (-2 and -1) to reduce the sensitivity. The sensitivity by the depth consists of two levels: S (shallow) and D (deep). Select shallow when scanning the object at a depth less than 10 cm and deep when scannning the object at a depth of 10 cm or more. The setting AS (A Shallow) is appropriate for scanning the steel bar at the depth less than 10 cm in the normal concrete. The initial sensitivity setting (default) at the factory shipment is AS (A Shallow). y The setting made by [Sensitivity] icon is valid only for the scan result displayed at the idlestate. After starting a new scan, the setting for the measurement is restored to the original device setting.. For the setting as the device setting, refer to Section 4.11.2 Device setting: [Sensitivity] menu. y When NJJ-200 application boots up, the sensitivity setting is set to the same as the settings of the device setting.

55 4.10.1. Image processing The original scan data includes always unnecessary reflected signals (for example, the reflection wave from the concrete surface (surface reflection wave) or reflection wave from the boundary of concrete layers) which is commonly distributed over the scan image. These unnecessary reflection waves make the image decoding difficult. Image processing aims to remove or reduce the unnecessary reflection waves by data processing (subtraction, averaging, and so on) and to provide easy deciphering of objects that are being probed from the scan result. This product supports the image processing listed in Table 4-2. Three image processing can be performed in real time during scanning. The other image processing are applicable to the scan result only at the idle state. Peak processing is applied to the image data obtained by an image processing. Table 4-2 shows which image processing is applicable in real-time during scanning and can be combined with the peak processing. For the image processing applicable at the idle state, refer to Section 4.10 [Image processing] icon. For the image processing applicable in real-time during scanning, refer to Section 4.11.4 Device setting: [Image processing] menu. This section describes the details of each image processing.

56 4.10.2. Fixed surface processing This image processing subtracts the predefined data of the typical concrete surface reflection wave from the displayed scan data. Usually it can reduce the concrete surface reflection wave to provide easy image decoding. The predefined data used in this image processing is called the fixed surface reflection wave which is generated at the factory by using typical concrete and is stored in the non-volatile memory of the sensor unit. y The scan result file stored into the data storage contains the raw scan data, the information about the selected image processing, and the fixed surface wave data used for the image processing. When the data is recalled from the file, NJJ-200 application displays the scan image by using the recalled data (raw scan data, the image processing setting, and the fixed surface wave data). After scanning, NJJ-200 application displays the scan image obtained by performing the selected image processing and the fixed surface wave data prepared in the sensor unit. 4.10.3. User surface processing This image processing subtracts the user defined surface reflection wave from the raw scan data. The user defined surface reflection wave is registered by selecting a point in the actual scan data. Then this image processing subtracts the actual reflection wave selected in the scan data, so that it can reduce the affection (noise) of the concrete surface reflection wave more accurately than the fixed surface wave processing. The user surface reflection wave can be defined and registered by the following procedure. (1) Scan the concrete. After the scan completed, the scan result image is displayed on the screen. (2) Move the cursor to the area on the scan result image where you want to do the processing. Make sure not to put the cursor directly on the point with a reflection signal (echo) from any embedded objects. (3) Tap [Image processing] icon. Then the image processing setup screen appears. (4) Tap User surface processing and confirm that the mark ● is attached to the selected setting. Then tap [□Processed at the current cursor.] and confirm that a mark 9is displayed in the [□]. (5) Tap [OK]. Then a message “Are you sure to update the user surface wave data?” [Cancel] [OK] appears. Tap [OK]. (6) A message “Saving user surface wave data completed” appears. Then tap [OK] to return to the main screen. Note

58 y The data file in the data storage contains the raw scan data, the image processing setting, and the fixed surface wave data used in the image processing. When the data is recalled from the data file, the scan result image is displayed by using the recalled data (raw scan data, the image processing setting, and the fixed surface wave data). However, the NJJ-200 application will displayany newly scanned images by using the image processing and the fixed surface wave data prepared in the sensor unit’s settings. y You can register a point in the recalled scan result as the user surface wave. After recalling the scan result, perform the procedure above to register a point of the recalled scan result as the user surface wave. y When the point showing some reflection signal from the embedded object is registered as the user surface wave, the image processing may produce unwanted noise on the scan result image. y When the unwanted noise appears after the image processing, register a different point with no reflection signal on the scan result as the user surface wave. Note
59 4.10.4. Subtraction This image processing is used to reduce the horizontal band noise of the reflection wave appearing at the depth more than 20 cm as shown Figure 4-16 1). You can use this image processing with the procedure below. (1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen. (2) Move the cursor to the area on the scan result image where you want to do the processing. Make sure not to put the cursor directly on the point with a reflection signal (echo) from any embedded objects. (3) Tap [Image processing] icon. Then the image processing setup screen appears. (4) Tap [Subtraction] and confirm that the mark ● is attached to the selected setting. Then tap [□Processed at the current cursor.] and confirm that the mark 9is displayed in the [□].

To change the reflection wave data used for the processing, perform the steps 2) to 4) above. y For the real-time subtraction processing, refer to Section 3.4 Interpreting the scan result. y The processing of the manual surface processing is almost same as that of the subtraction processing. The difference is that the manual surface processing subtracts the surface reflection wave data from the scan result only for the depth range of 0 mm to 200 mm. The subtraction processing subtracts the surface reflection data from the scan result over all depth range. y The subtraction processing may remove the reflection wave from the opposite side of the concrete wall. y For the manual surface processing, refer to Section 4.10.5 Manual surface processing. y When the registered surface reflection wave contains some signal reflected from the embedded object, the processing may produce the unwanted noise. Note )
61 4.10.5. Manual surface processing This image processing is used to reduce the remained noise even after an image processing (Refer to Figure 4-17 1)) . This image processing subtracts the registered surface reflection wave from the scan result only for the depth range of 0 mm to 200 mm. You can perform this image processing with the following procedure. (1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen. (2) Move the cursor to the area on the scan result image where you want to do the processing. Make sure not to put the cursor directly on the point with a reflection signal (echo) from any embedded objects. (3) Tap [Image processing] icon. Then the image processing setup screen appears.

Peak processing This image processing is effective to remove the unwanted image caused by the ringing in the reflection wave from the detected object (steel bar) and to show the refection wave only from the detected target. Use this processing when the depth of the detected object is difficult to read due to the images of the ringing. This processing is not applicable to the detection of the object (ex. cavity) with the relative permittivity lower than that of the concrete. This processing is applicable to the processed image obtained by fixed surface wave processing (including real-time surface wave processing), average processing, subtract processing, manual surface wave processing, user surface wave processing, or the original image.
