Thermal diffusivity determination using heterodyne phase insensitive transient grating spectroscopy
The elastic and thermal transport properties of opaque materials may be measured using transient grating spectroscopy (TGS) by inducing and monitoring periodic excitations in both reflectivity and surface displacement. The “phase grating” response encodes both properties of interest, but complicates...
