| Abstract: | This paper analyzes the possibility of extending the photothermal methods developed for thermal diffusivity measurements of isotropic materials to the case of anisotropic sample. A photodeflection method to determine ansotropic diffusivities is presented. The accuracy of both photothermal methods are also evaluated. |
