Abstract
The theory and experiment techniques about measuring the thermal diffusivity of solid materials by using laser induced transient reflecting grating is introduced. Comparison between experiment results and the data in literature demonstrates that it is a non-contact, nondestructive, rapid and exact approach to measure the thermal diffusivity of opaque solid materials.
