Abstract
Method and apparatus for improving the efficiency of laser scanning systems using a multifaceted rotating polygon or pyramid as the scanner. In particular, a beam of light, such as that generated by a laser beam, is directed onto a first facet of the scanner. This beam is expanded and reflected back to the same facet or any other facet on the scanner by optical means positioned adjacent the scanner so that the beam is caused to follow the facet of the scanner upon which the beam is reflected during a complete scan and to shift to the next facet for the following scan.
