Meta projector and electronic apparatus including the same

A depth recognition apparatus comprising:

• a meta projector;
• a first sensor disposed in a first position with respect to the meta projector, and configured to receive light from an object ;
• a second sensor, disposed in a second position with respect to the meta projector, different from the first position, and configured to receive light form the object;
• and
• a processor configured to analyze the light received by at least one of the first and second sensors and thereby calculate a depth position of the object,
• wherein the meta projector comprises:
• an edge emitting device disposed on a substrate, the edge emitting device comprising an upper surface extending parallel to the substrate and a side surface inclined relative to the upper surface, the edge emitting device configured to emit light through the side surface;
• a meta-structure layer spaced apart from the upper surface of the edge emitting device, the meta-structure layer comprising a plurality of nanostructures, each of the plurality of nanostructures having a dimension that is 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 to direct the path toward the meta-structure layer.
