An afocal sensor assembly detects a light beam with an aberrated wavefront. The afocal sensor assembly is configured to provide sorted four-dimensional (4D) light field information regarding the light beam, for example, via one or more plenoptic images. Based on the 4D light field information, a lossy reconstruction of an aberrated wavefront for one or more actuators of an adaptive optics (AO) device is performed. The AO device can be controlled based on the lossy reconstruction to correct the wavefront of the light beam. In some embodiments, the aberrated wavefront is due to passage of the light beam through atmospheric turbulence, and the lossy reconstruction and correction using the AO device is performed in less than 1.0 ms. The lossy reconstruction of the aberrated wavefront can have a phase accuracy in a range of λ/2 to λ/30.

A computational pixel imaging device that includes an array of pixel integrated circuits for event-based detection and imaging. Each pixel may include a digital counter that accumulates a digital number, which indicates whether a change is detected by the pixel. The counter may count in one direction for a portion of an exposure and count in an opposite direction for another portion of the exposure. The imaging device may be configured to collect and transmit key frames at a lower rate, and collect and transmit delta or event frames at a higher rate. The key frames may include a full image of a scene, captured by the pixel array. The delta frames may include sparse data, captured by pixels that have detected meaningful changes in received light intensity. High speed, low transmission bandwidth motion image video can be reconstructed using the key frames and the delta frames.

A camera assembly includes an infrared laser system, a camera, a flicker detector, and a light-filtering piece. The infrared laser system has an out-light surface. Infrared emitted by the infrared laser system propagates outside of the camera assembly through the out-light surface.

The light-filtering piece covers the in-light surface of the flicker detector and is configured to filter out infrared. The flicker detector is configured to detect a frequency of visible light in external light filtered by the light-filtering piece. When the camera assembly is applied to an electronic device, photographing performance of the electronic device is good.
