    摘要: A meta projector includes an edge emitting device configured to emit light through a side surface thereof, a meta-structure layer spaced apart from the upper surface of the edge emitting device that includes a plurality of nanostructures having a sub-wavelength shape dimension smaller than a wavelength of the light emitted from the edge emitting device, and a path changing member configured to change a path of the light emitted from the edge emitting device so as to direct the path toward the meta-structure layer. The meta projector may thus be configured to emit a light pattern of structured light, based on directing the light emitted from the edge emitting device through the meta-structure layer, while having a relatively compact device size.

    摘要: Provided are a structured light projector that generates and projects structured light, and an electronic apparatus including the structured light projector. The structured light projector includes an illuminator configured to emit light, a pattern mask configured to form structured light by partially transmitting and partially blocking incident light from the illuminator based on a pattern of the pattern mask, and a lens configured to project the structured light. The illuminator includes a plurality of illumination areas respectively facing a plurality of areas of the pattern mask, wherein intensities of lights respectively emitted by the plurality of illumination areas are different from one other.
