Abstract
An imaging apparatus including a means for converting graphic indicia into an electrical representations, a source of a coherent beam of optical radiation at a predetermined wavelength, a modulator for controlling the transmissive characteristics of a crystal which modulates the coherent beam in response to the electrical representations, a light deflector for scanning the modulated coherent beam in a scan pattern forming an image on a surface and means for developing the image from the surface and imaging a representation of graphic indicia by controlling the modulation and scanning of a coherent beam of optical radiation in a controlled pattern forming an image on a surface representative of the graphic indicia and developing the image.
