| A meta projector includes a light source array configured to emit light along an optical path. The light source array includes a first light-emitting array including a plurality of first light-emitting configured to emit first light having a first set of light properties and a second light-emitting array including a plurality of second light-emitting elements configured to emit a second light having a second set of light properties, the second set of light properties different from the first set of light properties. The meta projector includes a meta-structure layer aligned with the optical path. The meta projector includes a plurality of nanostructures having a subwavelength shape dimension that is smaller than a wavelength of light emitted from the light source array. The meta-structure layer is configured to differently modulate the first light and the second light in relation to each other. |
