Abstract: Provided are a nanostructured optical element, a depth sensor, and an electronic device. The nanostructured optical element includes: an array of a plurality of laser sources; a meta-pattern layer including a two-dimensional array of plurality of first nano-posts; and a deflecting layer between the light source and the meta-pattern layer. Each of the first nano-posts has a dimension smaller than a wavelength of light output from the plurality of laser sources. The deflecting layer is configured to direct light from the light source onto the meta-pattern layer.

Abstract: 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.

Abstract: A system and a method are disclosed for a structured-light system to estimate depth in an image. An image is received in which the image is of a scene onto which a reference light pattern has been projected. The projection of the reference light pattern includes a predetermined number of particular sub-patterns. A patch of the received image and a sub-pattern of the reference light pattern are matched based on either a hardcode template matching technique or a probability that the patch corresponds to the sub-pattern. If a lookup table is used, the table may be a probability matrix, may contain precomputed correlations scores or may contain precomputed class IDs. An estimate of depth of the patch is determined based on a disparity between the patch and the sub-pattern.
