Abstract:

The general features and theoretical framework of the photoacoustic effect have been reviewed in a comprehensive fashion recently. In the case of solids, much of the theoretical understanding is based on the work of Rosencwaig and Gersho which postulated that the absorbing solid behaved as a simple thermal piston on the coupling gas medium to produce the necessary pressure variation. In this theory, which is largely one dimensional, the PAS signals produced depend on a series of thermal and surface parameters of the solid sample, the solid-gas interface and to a lesser extent of the carrier gas itself.
