Abstract.

We extend the applications of photothermal diagnostics to solid spheres, in which both theoretical and experimental PTR studies on spherical geometries and thermal diffusivity of the sample are discussed. Based on the Green function method, a full thermal-wave field distribution of a spherical solid is obtained. Experimental results with steel spheres of different diameters exhibit good agreement between the theory and the experiments.
