Paper Abstract

A real-time, non-photographic, high-resolution Laser Microprinter without photographic film and processing is presented. It produces permanent 35 millimeter slides of special metallic thin-films, by means of laser scanning of 81/2" x 9" half-tone pictures. Laser scanning occurs with a rotating drum system. Transfer of the original picture content takes place by means of AM/PDM conversion of the backscattered reading laser intensity, to pulse-duration modulation of the printing laser. Actual Laser Microprinting comprises 20 linear density steps of 0.1, by means of changing the "hole" size in the metal thin-film of the microprint.
