    Abstract: A method of measuring a distance by using a 3-dimensional (3D) depth sensor is provided. The method may include: measuring m number of frames using light modulated at a first frequency to determine a first tentative distance from a viewpoint to an object at the first frequency, m being a positive integer; measuring n number of frames using light modulated at a second frequency to determine a second tentative distance from the viewpoint to the object at the second frequency, n being a positive integer, a sum of m and n being four; and determining a resulting distance to the object based on the first distance and the second distance.

    Abstract: Provided are meta-surface optical device and methods of manufacturing the same. The meta-surface optical device may include a meta-surface arranged on a region of a substrate and a light control member arranged around the meta-surface. The light control member may be arranged on or below the substrate. A material layer formed of the same material used to form the meta-surface may be disposed between the light control member and the substrate. Also, the meta-surface may be a first meta-surface arranged on an upper surface of the substrate, and a second meta-surface may be arranged on a bottom surface of the substrate. Also, the meta-surface may include a first meta-surface and at least one second meta-surface may formed on the first meta-surface, and the light control member may be arranged around the at least one second meta-surface.

    Abstract: A meta projector is provided, including 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 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.
