ABSTRACT:
An imaging system is provided for scanning stationary objects in an object plane and projecting the image onto a moving flat photoreceptor in such a manner that the image moves in a direction opposite the photoreceptor movement. In a preferred embodiment, the scanning illumination elements comprise a modified dual rate mirror system where the second mirror is moving at less than 1/2 the speed of the scan mirror thereby causing a resultant increase in platen-to-lens distance. This increase is compensated for, and image precession obtained, by moving the lens and mirror assembly along the optical axis in a direction opposed to that of the photoreceptor.
