Abstract: Aspects of the present disclosure relate to systems and methods for structured light (SL) depth systems. A depth finding system includes one or more processors and a memory, coupled to the one or more processors, includes instructions that, when executed by the one or more processors, cause the system to capture a plurality of frames based on transmitted pulses of light, where each of the frames is captured by scanning a sensor array after a respective one of the pulses has been transmitted, and generate an image depicting reflections of the transmitted light by combining the plurality of frames, where each of the frames provides a different portion of the image.

Abstract: Aspects of the present disclosure relate to systems and methods for active depth sensing. An example device includes a light projector. The light projector includes a light source to emit light and a diffractive element. The diffractive element is configured to receive the emitted light that is polarized, project a first distribution of light when the received light has a first polarity, and project a second distribution of light when the received light has a second polarity.

Abstract: A high dynamic range solid state image sensor and camera system are disclosed. In one aspect, the solid state image sensor includes a first wafer including an array of pixels, each of the pixels comprising a photosensor, and a second wafer including an array of readout circuits. Each of the readout circuits is configured to output a readout signal indicative of an amount of light received by a corresponding one of the pixels and each of the readout circuits includes a counter. Each of the counters is configured to increment in response to the corresponding photosensor receiving an amount of light that is greater than a photosensor threshold. Each of the readout circuits is configured to generate the readout signal based on a value stored in the corresponding counter and a remainder stored in the corresponding pixel.
