Application of the topological derivative to post-processing infrared time-harmonic thermograms for defect detection

Abstract This paper deals with active time-harmonic infrared thermography applied to the detection of defects inside thin plates. We propose a method to post-process raw thermograms based on the computation of topological derivatives which will produce much sharper images (namely, where contrast is...
