Abstract

An optical scanner which introduces a 'horizontal' scan component into combined 'read' and 'write' beams from a laser while introducing no 'vertical' angular component. The beams are subsequently passed through a field flattening objective lens and then are separated for passage to a read platen and exposure or write platen respectively. The scanner has a scanning wheel in the form of triangular regular pyramid cut from a circular disc, its sides (faces) constituting planar reflector segments. The faces deflect the combined beams by one half of the pyramid's angle. Adjacent the scanning wheel is a roof reflector doublet mirror by which the beams are returned to the scanning wheel from which the beams are again reflected a second time. As each segment rotates through the beams' path its varying angular orientation introduces horizontal and vertical components of angular deviation into the beam, the horizontal angular component being doubled upon the second (output) reflection from the wheel segment while the vertical component is cancelled by inversion through the roof reflector doublet. <IMAGE>
