Paper Abstract

The Scophony Light Valve when used in a laser scanner exhibits a coherent imaging response. Because of this coherent response, electronic manipulation of the acoustooptic modulator's drive signal can produce unique optical imaging effects, effects which cannot be achieved with the flying spot scanner architecture. An example of this electronic processing is a shift in the plane of best focus of the scanner which is achieved by passing the modulator's drive signal through a chirp filter. This electronic focus shift can enable a three dimensional television display.
