Abstract

The analytical developments in the Wong-Fung-Tam-Gao radiation model of thermal diffusivity were discussed. The photothermal deflection of the probe beam was determined by the heat radiation field contributed by the film and the substrate, heated by the pump beam. The two-dimensional algorithm was presented in order to deduce the measure of the diffusivities of the film and the substrate in one set of mirage detection from the experimental data.
