OPTICAL SYSTEMS CONFIGURED TO GENERATE MORE CLOSELY SPACED LIGHT BEAMS AND PATTERN GENERATORS INCLUDING THE SAME

摘要

An optical arrangement includes a focusing lens and a plurality of light sources. The focusing lens is configured to focus a plurality of light beams to form an array of virtual light sources in an image plane. The plurality of light sources are configured to emit the plurality of light beams such that the light beams cross each other in a plane.
