Claim 0:
1. A structured light projector comprising:
a light source configured to emit light, the light source comprising a plurality of light-emitting elements; and
a nanostructure array configured to form a dot pattern based on the light emitted by the plurality of light-emitting elements, the nanostructure array comprising a plurality of super cells,
wherein each of the plurality of super cells comprises a plurality of sub cells which are sub-divided areas of each of the plurality of super cells, wherein each of the plurality of sub cells comprises a plurality of nanostructures, and
wherein a distance between the light source and the nanostructure array is determined by a lattice constant of the plurality of super cells and a central wavelength of the light emitted by the light source.
