AbstractAn image processing algorithm based on a combination of the most commonly used signal processing techniques in pulsed thermography is applied to monitor the progression of impact damage sites during the full-scale testing of a composite test article. It is demonstrated that the algorithm can be used to monitor damage during a durability and damage tolerance testing. Over the first phase of the test program, although no damage growth was detected, the processed pulsed thermography images showed that the average standard deviation of the measurements was only ~0.08 inches, the equivalent of 2 infrared camera pixels.
