Open the CIPO recordAbstract From the Canadian patent
An optical system for strip scanning of an object in both directions of relative reciprocal motion between the object and the optical system. The object is first scanned in one direction, then the optical axis between object and image is rotated 180° for scanning in the reverse direction. Properly oriented images are thus projected onto a photoreceptor during both directions of scan.
