ABSTRACT:
A system is disclosed for transforming a collimated beam of light into a beam of light which repetitively scans a fixed path by utilizing first and second mirrors repetitively rotated through a predetermined angular displacement. The angle between each mirror facet and mirror axis of rotation varies and defines a facet to axis error which is eliminated by the present invention. A first mirror receives an upper input beam and repetitively generates a first scan. A second mirror receives a lower input beam and repetitively generates a second scan. First and second redirecting means such as first and second prisms form first and second redirected scans which are ultimately reflected from the mirrors to generate a plurality of first and second output scans. A lens converges the first and second output scans onto a fixed path such that the scanner optical output beam repetitively scans the fixed path and eliminates the effect of the facet to axis errors of the first and second mirrors.
