SanjAnalyzer PLUS – Image Processing

SanjAnalyzer PLUS – Image Processing

SanjAnalyzer PLUS is the companion application used to open and process saved calibration, transient, and steady-state image files. Its main view includes a File Window, a Working Image pane, a Reference Image pane, and an Image Calibration Window. [diagram/image in source — not reproduced here]

1. Open Calibration Image
   1. Open the file location where all test images are saved.
   2. Open the Calibration Image file.
   3. Check Correct XY to correct for thermal expansion.
2. Save Calibration Image
   1. Click Save Images/Data.
   2. Change Image Save Format to TTI.
   3. Click Save Image (Current VIEW) to capture the image.
   4. If TTI is already selected, click Quicksave instead.
3. Open Transient Image
   1. Click Open File.
   2. Select Refresh to update the file list with the corrected Calibration Image.
   3. Open the Transient Image file (double-click).
   4. Select Point by Point — the Load Cth Map dialog will pop up.
   5. Select the corrected Calibration Image file from the browse dialog and click LOAD.
4. Measuring ΔT
   1. Using the rectangle tool, drag the ROI box across the length of the specimen to measure temperatures in that range. You can draw up to 5 ROI boxes to measure and compare temperatures at different locations on the specimen.
   2. Select Thermal Cross-Section.
   3. Click Rectangular Profile to see the rectangular profile of the temperatures within the ROI box.
      • Note on the ROI boxes shown in the source example image: a green ROI box measures ΔT along the length of the specimen line; a yellow ROI box measures peak temperature.
5. Measuring ΔT – Alignment Accuracy
   1. If an accurate ΔT is desired on smaller features, increase the Alignment % used during the calibration process. This increases the time required for the measurement but provides better results. [diagram/image in source — not reproduced here — shows a more accurate result obtained with a higher Alignment %]
   2. Be aware that a less accurate measurement can result from a misaligned or moved device: the source example shows red lines appearing as a result of the device not being properly aligned and/or movement of the device. [diagram/image in source — not reproduced here]
