A simple, coherent-optical processor for the production of colour-encoded images from half-tone screened, black and white transparencies is described. Only one laser is used, and the images generated when different diffracted orders and selected by a spatial filter are picked up by a black and white, closed-circuit television system. The screen of the monitor is photographed successively through appropriate coloured filters to produce a colour-encoded image.
