Abstract

A structured light illumination module is provided and includes a light source including a laser diode and configured for emitting light; an optical element including a light transmissive part which receives light and allows collimated light to pass, and a total internal reflection part, wherein an angle θ between a reflective surface of the total internal reflection part and an optical axis of the optical element is configured for totally internally reflecting a part of the light by the reflective surface; a diffractive component configured for converting the light into a structured light pattern; and an energy recycling mechanism disposed on at least a part of an incident surface or an emergent surface of the optical element.
