Paper Title:
Characterizing the Thermal Properties of Solid Materials with Weakly Absorption by the Transient Thermal Grating Method
  Abstract

In this paper, a perpendicularly overlapped transient thermal grating (TTG) method is proposed to characterize the weakly absorptive or poorly reflective materials. Based on the Kirchhoff’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 the simulation results shows, the diffraction ability of the perpendicularly overlapped TTG is much better than that of the TTG method, and much suitable to characterize the thermal properties of opaque sample with weak absorptivity or poor reflectivity.
