Abstract
A light modulator for use with a laser or laser diode array such that the light from the laser is imaged on a light modulator having a row of light modulating elements, either of the reflectance or transmittance type. The light modulator is imaged onto a light-sensitive material and the image is scanned line by line on the light-sensitive material. Control circuitry is provided to control the relative movement between the light modulator and the light-sensitive material that may be either in planar form or wrapped out the circumference of cylindrical drum.
