US Patent 11428788 Laser measurement module and laser radar

Embodiments of this application disclose a laser measurement system and a laser radar. In one aspect, a laser measurement system includes N laser ranging components, a reflector, and MEMS micromirror. The N laser ranging components can emit an emergent light beam onto the reflector. The reflector can perform optical path reflecting on the emergent light beam and emit the reflected emergent light beam onto the MEMS micromirror. The MEMS micromirror can change a direction of the emergent light beam to implement two-dimensional scanning, change a direction of an echo light beam, and emit this beam onto the reflector. The reflector can perform optical path reflecting on the echo light beam and emit this beam onto the N laser ranging components. The N laser ranging components can receive the echo light beam and perform ranging based on a time difference between the emergent light beam and the echo light beam.
