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.
