Abstract:
Imaging apparatus is disclosed for exposing a recording medium to produce an image in accordance with information contained in an electrical signal. The apparatus comprises a light source, optical means for imaging light onto the recording medium, and a light-valve array to control the light reaching selected areas of the recording medium. The light valve-array is comprised of a plurality of electrostatically deflectable elements each of which contains a waveguide for transmitting light from the source to a receptor waveguide. Light from the receptor waveguides is imaged onto the recording medium. In order to provide for gray scale in the image, a control means is provided to precisely control the amount of deflection of the elements and thereby control the amount of light transmitted for a given pixel.
