2D SCANNING HIGH PRECISION LiDAR USING COMBINATION OF ROTATING CONCAVE MIRROR AND BEAM STEERING DEVICES
First Claim
1. A light detection and ranging (LiDAR) scanning system, comprising:
- a first light source configured to provide one or more first light pulses; and
one or more beam steering apparatuses optically coupled to the first light source, each beam steering apparatus comprising a rotatable concave reflector and a light beam steering device, wherein the combination of the light beam steering device and the rotatable concave reflector, when moving with respect to each other, is configured to;
steer the one or more first light pulses both vertically and horizontally to illuminate an object within a field-of-view,obtain one or more first returning light pulses, the one or more first returning light pulses being generated based on the steered first light pulses illuminating an object within the field-of-view, andredirect the one or more first returning light pulses to one or more receiving optical systems disposed in the LiDAR scanning system.

Abstract
The present disclosure describes a system and method 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 apparatuses optically coupled to the first light source. Each beam steering apparatus comprises 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 with respect to each other, steers the one or more first light pulses both vertically and horizontally to illuminate an object within a field-of-view; obtain one or more first returning light pulses, the one or more first returning light pulses being generated based on the steered first light pulses illuminating an object within the field-of-view, and redirects the one or more first returning light pulses.
