Abstract: A method for depth mapping includes operating a projector at a first temperature to project a pattern of optical radiation onto a reference plane, capturing a first image of the projected pattern on the reference plane, using the first image and an optical and thermal model of the projector to compute multiple reference images associated with different respective temperatures of the projector. Using the projector, the pattern is projected onto a scene, and a temperature of the projector is measured while projecting the pattern. The method further includes capturing a second image of the projected pattern on the scene, selecting one of the reference images responsively to the measured temperature; and computing a depth map of the scene by comparing the pattern in the second image to the selected one of the reference images.

Abstract: An optoelectronic apparatus includes an array of emitters configured to emit beams of optical radiation. An optical substrate is mounted over the array. An optical metasurface is disposed on the optical substrate and configured to collimate and split each of the emitted beams into a respective group of collimated sub-beams, and to direct the collimated sub-beams toward a target to form a pattern of spots on the target.

Abstract: An optoelectronic apparatus includes a substrate and first and second arrays of emitters disposed on the substrate and configured to emit respective first and second beams of optical radiation. The apparatus further includes an optical metasurface disposed on the substrate and configured to collimate and diffuse the first beams without diffusing the second beams, and an optical projection element, configured to intercept both the first and the second beams that have passed through the optical metasurface and to direct both the first and the second beams toward a target while focusing the second beams to form a pattern of spots on the target.
