2D LiDAR2D SCANNING HIGH PRECISION LiDAR USING COMBINATION OF ROTATING CONCAVE MIRROR AND BEAM STEERING DEVICES

摘要

This disclosure describes systems and methods for coaxial LiDAR scanning. The system includes a first light source configured to provide first light pulses. The system also includes one or more beam steering devices optically coupled to the first light source. Each beam steering apparatus includes a rotatable concave reflector, and a light beam steering device disposed at least partially within the rotatable concave reflector. The combination of the light beam steering device and the rotatable concave reflector, when moving relative to each other, steers one or more first light pulses both vertically and horizontally to illuminate objects in the field of view, and steered to illuminate objects in the field of view. One or more first return light pulses generated based on the first light pulses are acquired, and one or more first return light pulses are redirected.
