Profile Reconstruction in Dynamic Infrared Thermography: Adaptability and Stability

An iterative algorithm for solving geometric inverse problem in dynamic infrared thermography has been proposed in this paper. According to 1D dynamic heat-conduction model and the corrective criterion based on Tailor's series expansion, both 2D and 3D geometrical inverse problems are solved by following an iterative procedure. Computer simulation results show that the reconstructed profile has satisfactory accuracy. The adaptability and stability of the method are also discussed.
