Photodetection Lidar with multiple receivers

摘要

PROBLEM TO BE SOLVED: To provide a lidar device capable of including a transmitter, first and second receivers, and a rotating platform. A transmitter may be configured to emit light having a vertical beamwidth. The first receiver may be configured to detect light with a first resolution while scanning the environment with the first FOV, and the second receiver may be configured to scan the environment with the second FOV and the second. It can be configured to detect light with resolution. In this configuration, 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 beamwidths may be at least the first and first. It may include a vertical range of 2 FOVs. Further, the rotation platform may be configured to rotate about an axis such that the transmitter and the first and second receivers move based on their rotation, respectively.
