Abstract

The results of inverse problem solution for photothermal diagnostics of inhomogeneous medium are presented. Fast, effective algorithm for layered medium is considered. The method is valid for relatively wide range of differential equations and gives fast reconstruction of 1D thermal parameter profiles for the case of smooth inhomogeneities of arbitrary value. The numerical simulation results are also given. The represented stochastic approach is valid for thermal parameter fluctuations of arbitrary depth.
