Abstract
An iterative algorithm for solving nonlinear inverse problems in the photothermal detection is presented. The basic idea of the algorithm is that the nonlinear inverse problem in the frequency domain is solved by a hybrid of Newton-like iterative method, pseudoinverse technique, and finite difference method. The numerical simulation shows the algorithm is effective for profile reconstruction of the thermal conductivity in the case of errorless data.
