ABSTRACT:
Apparatus and methods for making displays, printing plates, electrical circuit boards, and generally reproductions of originals in reduced, enlarged or full size comprising generating a collimated beam of interrogating light; optically deviating and raster scanning the beam and a recording beam; and receiving light from the object adjacent the scan line and transmitting said received light to a photodetector to generate an electrical signal representative of the light from the object using a fiber optic line to spot converter. Any photosensitive recording medium; a photocurable composition, a thin metal ablative film, silver halide film, an electrostatically charged photoconductor, thermoplastic deformation material or other physically or chemically alterable media, including ovonic, liquid crystal, photochromic or vesicular films, can be used.
