A lensless acousto-optical convolver has been realised with surface acoustic waves, which relies on a technique of polarisation discrimination detection of the diffracted light. A polariser may, then, filter the light signal directly in the Fresnel field, thus allowing realisation of a strictly compact device that retains properties of easy adjustment and simplicity.
