Abstract

In our paper, a theoretical treatment which includes a new and effective numerical method is proposed. It is used to nondestructively reconstruct the depth distribution of optical absorption coefficient in multilayer inhomogeneous material, through by the photothermal signal which is related to the surface temperature of a sample and measured with the photothermal method. Numerical simulations demonstrate the performance of the approach is better.
