MULTI-BEAM SCANNER AND CONFOCAL OPTICAL SYSTEM INCLUDING THE SAME

摘要

A multi-beam scanner may include a scan lens and a reflecting mirror. The scan lens may have eccentric incidence points offset from a center point of the scan lens to which at least two light beams may be irradiated. The scan lens may be configured to concentrate the light beams. The concentrated light beams may be incidence to the reflecting mirror. Thus, an object may be scanned by the light beams using only one scan lens so that the multi-beam scanner may have a less complex structure.

主权项

1. A multi-beam scanner comprising:
a scan lens having at least two eccentric incidence points to which at least two light beams are directed, wherein the scan lens is configured to focus the at least two light beams to a location; and a reflecting mirror positioned at the location and configured to reflect the at least two light beams.
