| Abstract: | In order to obtain the harmonic temperature field in anisotropic material heated by a modulated Gaussian laser beam, the three-dimensional equations of heat conduction are solved by using Fourier transforms. The amplitude and phase response of the temperature variation as a function of the position on the surface and depth in the anisotropic material are studied. The influence of the material's optical and thermal properties on temperature distribution is discussed. Moreover, some useful results are achieved on measuring the thermal conductivity tensor. |
