Abstract

Disclosed is a device for electro-optical conversion of imagewise information. This device comprises a line of small electrodes attached to a layer of a field formable material which is coated with a flexible metal film, and in one embod- • iment the electrodes may be separated and the structure supported by an insulating substrate. With the electrodes addressed in an imagewise pattern, the metal film above the charged electrodes becomes a frosted sinusoidal diffraction grating. The deformed metal surface can be illuminated by a source of arbitrary intensity and color and the light reflected from the image area is defracted into beams which, subsequent to passing through the appropriate optical systems, expose the photoreceptor. By employing this system, nearly 100% diffraction efficiency is obtained. One method of • entering the imagewise electrical information is through the • use of a charge coupled device (CCD) which may also be used in the imaging mode to generate the electrical input.
