Abstract: A method for the high resolution sensing of a pattern of information so as to provide an output signal corresponding thereto includes the novel steps of optically generating an enlarged image of the pattern of information and sensing that enlarged image with a thin film photosensor array. By the use of optical enlargement, the effective resolution of the sensor array is increased. Apparatus utilizing this method may be employed in conjunction with printers or display devices to provide high resolution images of information being scanned.
