Damage Detection in Thin Plates via Time-Harmonic Infrared Thermography
Non-destructive damage detection has become a very active research topic recently. This paper is devoted to the processing of time-harmonic thermograms (color images of one side of the sample to be inspected, obtained by a thermal camera) for structural health monitoring of thin plates. Our approach is based on the evaluation of an indicator function, the so-called topological derivative, which will identify the regions inside the plate where damage is located.
