Abstract

We suggest a photothermal method for measuring thermal properties of opaque coatings. The coating-substrate assembly is irradiated by the repetitive pulse power laser which causes a nonstationary buckling of the coating. Thermal properties of the coating are determined by comparing the measured phase shift in the wave component of the temporal dependence of beam deflection angle of the low power laser with theoretical predictions obtained by solving equations of thermal elasticity.
