We present a theoretical model for characterizing the thermal-wave field of solid multi-layered spherical samples illuminated by a modulated incident beam. This theoretical model is developed by the analogous Green function method. The specific Green's function for the multi-layered spherical structure is obtained by analogy with those of 2-layer and 3-layer structure, and the analytical expression of the thermal-wave field in the multi-layered spherical sample is presented. The temperature field of an inhomogeneous spherical sample with incident light of arbitrary angular and/or radial intensity distribution can be obtained by this theoretical model.
