OPTICAL METHOD AND SET-UP FOR THE THERMAL DIFFUSIVITY MEASURMENT OF SOLID STATE MATERIALS

Abstract

Application of light-induced thermal transient gratings for measurement of thermal diffusivity of solid state materials including thin films is presented. Laser-optical set-up, which allows non-contact measurement of thermal diffusivity by transient gratings′ method is described. The set-up was designed in B.I. Stepanov Institute of Physics of NAS of Belarus.
