Application of the temperature distribution formula for the photoacoustic investigations of layer systems

Abstract

This paper presents results of theoretical investigations of layer structures of the type: a thin semitransparent layer on the thick semitransparent substrate. Considerations presented in the paper comprise a derivation of the analytical expressions for the spatial distributions of the instantaneous temperature in the surface layer and the thermally semi infinitive substrate. These analytical expressions are of great importance as they enable computations of both frequency and spectral photoacoustic characteristics of several layer systems.
