Abstract:
A laser scanning system for generating a laser scanning pattern in a scanning field, while amplifying the scan-angle multiplication factor of rotating mirrors employed therein. The laser scanning system employs rotatable laser scanning assembly having an axis of rotation and first and second rotating mirrors with normal vectors that are coplanar with each other and said rotational axis, and which form an acute angle substantially less than 90 degrees so as to provide a laser scanning assembly with a scan angle multiplication factor that is greater than 2.0. A cluster of stationary mirrors mounted about the first and second rotating mirrors, for sweeping a laser beam off the cluster of stationary mirrors after a laser beam has been reflected off the first rotating mirror, then reflected off the second rotating mirror, and then directed outwardly towards an array of pattern mirrors, so as to generate a resultant laser scanning pattern within the scanning field.
