Abstract: Described herein is a LIDAR device that may include a transmitter, first and second receivers, and a rotating platform. The transmitter may be configured to emit light having a vertical beam width. The first receiver may be configured to detect light at a first resolution while scanning the environment with a first FOV and the second receiver may be configured to detect light at a second resolution while scanning the environment with a second FOV. In this arrangement, the first resolution may be higher than the second resolution, the first FOV may be at least partially different from the second FOV, and the vertical beam width may encompass at least a vertical extent of the first and second FOVs. Further, the rotating platform may be configured to rotate about an axis such that the transmitter and first and second receivers each move based on the rotation.

Abstract: The present disclosure relates to optical receiver systems. An example system includes a plurality of substrates disposed in an edge-to-edge array along a primary axis. Each respective substrate of the plurality of substrates includes a plurality of detector elements. Each detector element of the plurality of detector elements generates a respective detector signal in response to light received by the detector element. The plurality of detector elements is arranged with a detector pitch between adjacent detector elements of the plurality of detector elements. Each respective substrate of the plurality of substrates also includes a signal receiver circuit configured to receive the detector signals generated by the plurality of detector elements. The respective substrates of the plurality of substrates are disposed such that the detector pitch is maintained between adjacent detector elements on their respective substrates.
