Abstract
A structured light generator includes a light source configured to emit light, and a first meta optical device including a first metasurface including nanostructures having sub-wavelength dimensions that are less than a wavelength of the light emitted from the light source, the first metasurface being configured to form a distribution of light rays from the light emitted from the light source to thereby radiate structured light.

A structured light generator comprising:
- a light source configured to emit light;
- and
- a first meta optical device comprising a first metasurface comprising nanostructures having sub-wavelength dimensions that are less than a wavelength of the light emitted from the light source,
- wherein the first metasurface is configured to form a distribution of light rays from the light emitted from the light source to thereby radiate structured light;
- and,
- a second meta optical device provided between the light source and the first meta optical device, the second meta optical device comprising a second metasurface configured to adjust a beam shape of the light emitted from the light source.
