In order to achieve thick scale samples photothermal parameter distribution of inversion, an inversion model of photothermal parameters for thick scale sample is put forward and established. Theoretical calculation and numerical simulation for laser induced thermal, both forward and inverse problems, have been competed with photo-thermal technique, regularization method, Green function method and singular value decomposition method. Simulation results, which two light absorption layers are in thick scale sample, achieve success though the inversion signal gathered from the upper and nether surface of sample respectively. Results show the method has a good stability and usability.
