Abstract : Non-stationary thermal wave imaging (NSTWI) which is one of the techniques of Infrared Thermal Non-Destructive Testing (IRTNDT) plays a vital role in inspecting, evaluating and analyzing various materials. With excellent capabilities for surface and sub-surface crack and back holes detection, moderate peak power and taking less time in analyzing results when compared to lock in thermography and pulsed thermography, NSTWI excel in this domain. This paper highlights comparison of various NSTWI post-processing techniques, further experimentation is done to detect defects in composites. Signal to noise ratio of each post processing technique is considered and the best technique is chosen.
