Abstract
A system for reproducing a raster scanned line of an image on a photoconductive surface of a drum comprising a monochromatic light source, a rotating holographic disk containing a plurality of diffraction gratings therein, and means for reflecting said monochromatic light beam so as to direct the monochromatic light beam to and along a selected straight line on the photoconductive surface of the drum. The means for reflecting the monochromatic light beam comprises an elliptic reflecting surface, a first mirror for reflecting the monochromatic light beam passed through the scanning disk to said elliptic reflecting surface, and a second mirror for receiving the monochromatic light beam reflected from the elliptical reflecting surface and for directing the reflected light beam onto a selected straight line on the photoconductive surface of the drum. The elliptic reflecting surface can, with little loss in accuracy, be replaced by a cylindrical surface.
