C. Mattei et al., OPTICAL-DETECTION OF SURFACE ACOUSTIC-WAVES PROPAGATING ALONG AN INTERFACE BETWEEN 2 SOLIDS, Journal de physique. IV, 4(C5), 1994, pp. 745-748
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.
