Abstract
An output scanner for producing images in response to image signals, the scanner having a high intensity illumination lamp, fiber optic bundle for converting the light output of the lamp to a succession of light rays for exposing an imaging member line by line, an electro-mechanical modulator for modulating the light rays individually in response to image signals, and a lens array for transmitting light rays from the modulator to the imaging member. The modulator comprises a full width array of closely spaced finger-like reflectors which deflect upon application of a preset potential thereto, the potential being applied to the reflectors selectively in accordance with an image signal.
