Lock-in Thermography tests are performed without noise correction. Thus, the overlay of an LIT test will have noise in the image, unless noise correction is applied after the fact. Perform the following steps to remove the vertical line noise from the LIT overlay image:
- Unshow Overlay
- Turn on Noise
- Show Overlay
