Abstract
Aspects of the present disclosure relate to systems and methods for active depth sensing. An example device includes a light projector. The light projector includes a light source to emit light and a diffractive element. The diffractive element is configured to receive the emitted light that is polarized, project a first distribution of light when the received light has a first polarity, and project a second distribution of light when the received light has a second polarity.
