Abstract: Disclosed herein is an efficient optical scanning system takes the output of a multi-laser bar emitter with high divergence and delivers a combined beam of long vertical stripes of optical power that have a nearly top hat distribution along a vertical scanning axis and a narrow width along a horizontal scanning axis. This line footprint of the combined beam is scanned by a mirror onto a scene for use as ranging light in a distance measurement system.
