Abstract : The invention relates to an optoacoustic device which permits the transmission or reflection of a beam of light to be locally controlled by an acoustic surface wave. Such local control permits spatial modulation of the light beam by the acoustic surface wave. This interaction forms the basis for many useful signal processing devices, since the spatial light pattern corresponds to a portion of the time history of the signal used to generate the surface wave.
