Abstract

A laser printing system for illuminating an elongate region of a photosensitive surface. The laser printing system includes a laser source to generate a light beam in a light path and a light modulation assembly that includes an n×m array of elements, wherein the n×m array has an aspect ratio of at least 1:100. The laser printing system additionally includes an expansion assembly disposed in the light path between the laser source and the light modulation assembly to expand the light beam and impinge the light beam simultaneously on substantially all of elements in the n×m array of elements.
