Abstract
A method and system for generating light pattern using reflective polygons are provided herein. The method may include: rotating at least one polygon having a plurality of reflective facets along a rotation axis parallel to the facets; transmitting a light beam on the facets of the polygon; tilting the light beam relative to the polygon in parallel to the rotation axis so that the light beam hits each of the facets at a different tilt angle, thereby producing a light pattern comprising a plurality of lines; and controlling at least one of: the light intensity, the rotating, and the tilting, so as to produce an adjustable light pattern transmitted at a scene.
