Abstract: Example embodiments relate to selective deactivation of light emitters for interference mitigation in light detection and ranging (lidar) devices. An example method includes deactivating one or more light emitters within a lidar device during a firing cycle. The method also includes identifying whether interference is influencing measurements made by the lidar device. Identifying whether interference is influencing measurements made by the lidar device includes determining, for each light detector of the lidar device that is associated with the one or more light emitters deactivated during the firing cycle, whether a light signal was detected during the firing cycle.

Abstract: A Lidar system includes a focal-plane array having a plurality of pixels. Each pixel includes a first single-photon avalanche diode (SPAD) and a second SPAD. The Lidar system operates by, for each of a plurality of the pixels, applying a bias voltage to the first SPAD of the pixel while no bias voltage or low bias voltage is applied to the second SPAD of the pixel, then removing the bias voltage from the first SPAD of the pixel and applying a bias voltage to the second SPAD of the pixel while no bias voltage or low bias voltage is applied to the first SPAD of the pixel, and then recording detection of a photon by the first SPAD of the pixel and detection of a photon by the second SPAD on a common memory bank of the pixel.

Abstract: An integrated light detection and ranging (LiDAR) architecture can contain a focal plane transmitter array, and a focal plane coherent receiver for which the number of receiving elements is the same as the number of emitting elements. A microlens array may be used to achieve parity between the number of receiver and transmitter elements. The integrated LiDAR transmitter can contain an optical frequency chirp generator and a focal plane optical beam scanner with integrated driving electronics. The integrated LiDAR receiver architecture can be implemented with per-pixel coherent detection and amplification.

Abstract: A Lidar system includes an array of photodetectors. The system includes a beam-steering device and a light emitter aimed at the beam-steering device. The beam-steering device is designed to aim light from the light emitter into a field of illumination positioned to be detected by a segment of the array of photodetectors. The segment is smaller than the array. The system includes a computer having a processor and memory storing instructions executable by the processor to adjust the aim of the beam-steering device to move the field of illumination relative to the array of photodetectors.
