ABSTRACT OF THE DISCLOSURE An Optical scanning and imaging system util- izing laser diode light generation comprising; a solid state laser light generating device producing a divergent electromagnetic visible emission, means for collecting and collimating said divergent emission into a beam of light; means for optically shaping said beam to effectively expand the verticle dimension thereof; and for reducing the horizontal dimension of said beam; a rotatable polygon mirror assembly in the path of said light beam and having a plurality of flat mirror facets disposed around the periphery thereof; means for bringing said beam into sharp focus on a single facet of said rotatable ploygon mirror assembly; angularly, adjustably positionable, reflective means disposed adjacent to said polygon mirror assembly; a photoconductive drum rotatably disposed adjacent to said adjustably positionable reflective means, and focusing means interposed between said polygon mirror assembly and said adjustably positionable reflective means for bringing said beam into focus on said drum as said beam is moved by said polygon mirror assembly across the surface of said rotatable drum effectively causing said beam to scan said drum from side to side.
