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.

MOE-based illumination projector

One disclosed embodiment includes techniques for temperature-dependent reference image correction in structured light projectors that may be used for generating three-dimensional (3D) scene depth maps. The techniques disclosed herein include receiving an indication of a temperature (e.g., an actual current operating temperature or a change in the current operating temperature relative to an established reference temperature) associated with one or more components of a projector and then determining, based on the temperature indication, an amount of adjustment needed to correct a reference pattern image based on an estimated effective focal length change of the projector. Next, a reference pattern image may be appropriately adjusted, e.g., based on the determined amount of effective focal length adjustment caused by the current operating temperature of the projector, to generate a corrected reference image, which may then be used to generate a more accurate 3D scene depth maps at the projector's current operating temperature.
