Abstract:
An apparatus that includes a structured light projector which includes a light source, a metalens, and a diffractive optical element (DOE) multiplier. Each of the metalens and the DOE multiplier is integrated onto the light source. The structured light projector is operable such that light beams produced by the light source pass through the metalens and the DOE multiplier.
