Notes:
In this paper, a perpendicularly overlapped transient thermal grating (TTG) method isproposed to characterize the weakly absorptive or poorly reflective materials. Based on theKirchhoff’s law and thermal elastic theory, the theoretical distribution of the diffraction light in space,which modulated by the overlapped TTG method and TTG method, have been given. As thesimulation results shows, the diffraction ability of the perpendicularly overlapped TTG is much betterthan that of the TTG method, and much suitable to characterize the thermal properties of opaquesample with weak absorptivity or poor reflectivity
