STRUCTURED LIGHT PROJECTION USING A COMPOUND PATTERNED MASK

摘要

The present disclosure describes structured light projection in which a structured light projector includes a light emitter and a compound patterned mask. The mask includes a spacer substrate that is transparent to a wavelength of light emitted by the light emitter. On a first side of the spacer substrate is a first reflective surface having apertures therein to allow light to pass through. Lenses are arranged to focus light, produced by the light emitter, toward the apertures in the first reflective surface. A second reflective surface on a second side of the spacer substrate opposite the first side has apertures therein to allow light passing through the spacer substrate to exit the compound patterned mask.

1. A structured light projector comprising:
a light emitter; and a compound patterned mask including:
a spacer substrate that is transparent to a wavelength of light emitted by the light emitter;a first reflective surface on a first side of the spacer substrate, the first reflective surface having apertures therein to allow light to pass through;a plurality of lenses arranged to focus light, produced by the light emitter, toward the apertures in the first reflective surface; anda second reflective surface on a second side of the spacer substrate opposite the first side, wherein the second reflective surface has apertures therein to allow light passing through the spacer substrate to exit the compound patterned mask.
