Active infrared thermography is a nondestructive method for evaluating defects in artworks. A conventional excitation radiation heats the sample and the photothermal response is recorded by an infrared (IR) camera. Classical pulsed excitation has shown the feasibility of such a detection system, but the energy deposition for a long period of time can alter samples. Random excitations can prevent such problem, but signal processing methods should be implemented to extract the useful information… CONTINUE READING
