Abstract
InfraRed Thermography (IRT) is one of the promising Non-Destructive Testing (NDT) method for testing and evaluation of various solid materials. Due to its inherent inspection capabilities such as non-contact, fast, quantitative, and safe deployment in field testing makes active IRT as a vital testing technique in NDT community. The present work introduces a novel approach called Golay coded thermal wave imaging to examine a mild steel sample having flat bottom hole defects. Further frequency domain based post-processing scheme is implemented onto the pulse compressed reconstructed data to improve the detection capabilities of the considered approach.
