ABSTRACT:
A flying spot flat field scanning system is provided wherein a laser beam is directed to a polygon scanner which sweeps the beam via a pair of relatively movable mirrors across a document to provide a scan in an x direction. The mirrors move relative to one another across the document to provide a scan in a y direction and move at such a relative rate to maintain optical conjugates constant.
