激光光热散射技术测量不透明材料的热扩散率

A method to measure thermal diffusivity of opaque materials by a laser photothermal scattering technique is introduced in this paper. The thermal diffusivity can be fitted by amplitude and phase of the sample photothermal signal at different frequencies and the thermal diffusivity of nanometer Al2O3 at different sintering temperatures is measured by the method.
