Abstract

A depth sensing system including an electronic display, a light source, an array of optical sensing elements, and a depth map generator. The light source is configured to transmit periodic bursts of light in a field of view (FOV) of the depth sensing system. The array of optical sensing elements is disposed behind the electronic display and configured to detect light reflected from one or more objects in the FOV of the depth sensing system, where the reflected light is partially occluded by the electronic display. The depth map generator is configured to receive sensor data based on the detected light form the array of optical sensing elements and determine depth information about the one or more objects by applying one or more neural network models to the received sensor data.
