Abstract
We report an optical detection of interface waves based on the acousto -optic interaction. The variation of the index of refraction induced b y a wave propagating inside a transparent media is measured using inte rferometric detection. This index variation is related to the compress ional acoustic strain. We applied this detection method to study the p ropagation of interface waves under two kinds of boundary conditions ( slip or rigidly bonded) between the solid substrates.
