Imaging Modes - R‑Scan
This image was generated on a sample consisting of a tube soldered inside of another tube. With this type of inspection mode a cylindrical sample can be effectively unwrapped. As data is being captured from side to side the sample is also being rotated to access the entire area of interest. In this case the sample was rotated 360 degrees to inspect the entire attach. Note that the defects (bright white features) near the bottom of the image are also seen in the top of the image.
