ABSTRACT:
A light gate array in which each of the gates is individually controllable. Uniform light is gated through the array to form a dot-matrix image on a photosensitive material. The light gates have differing areas or shapes so that different light intensities are gated by the different gates. The array is useful when the same area of the photo-sensitive material is selectively exposed through multiple gates of different areas or shapes.
