1. A structured light projector comprising:
a light source configured to emit light having a first polarization;
a structured light pattern mask configured to receive the light emitted by the light source, the structured light pattern mask comprising a first region configured to generate a first structured light having the first polarization and a second region configured to generate a second structured light having a second polarization that is different from the first polarization; and
a polarization multiplexing deflector configured to deflect the first structured light and the second structured light generated by the structured light pattern mask, to different directions, respectively,
wherein at least one of the first region and the second region comprises a plurality of nanostructures.
