Abstract : This document discloses an acousto-optical modulator for modulating light with surface waves. Surface waves are excited on an aluminum plate which is tapered to terminate in a wedge type formation, the surface wave transmitted in the direction of the wedge. The waves are amplified by the wedge and transmitted to a membrane, which has been mirrored on one surface and stretched over a U shaped frame and part of the wedge. Light illuminating the mirrored surface is both spatially and temporally modulated by the surface waves transmitted through the wedge to the membrane.
