Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A laser measurement system, comprising N laser ranging components, a reflector, and a micro-electro-mechanical system (MEMS) micromirror, wherein:
N is a positive integer greater than or equal to 2;
each of the N laser ranging components is configured to emit an emergent light beam onto the reflector;
the reflector is configured to perform optical path reflecting on the emergent light beam, and emit the reflected emergent light beam onto the MEMS micromirror;
the MEMS micromirror is configured to (1) change a direction of the emergent light beam to implement two-dimensional scanning, (2) change a direction of an echo light beam, and (3) emit the echo light beam onto the reflector, wherein the echo light beam is a light beam reflected by the emergent light beam emitted onto a target object;
the reflector is further configured to perform optical path reflecting on the echo light beam, and emit the reflected echo light beam onto each of the N laser ranging components;
wherein an included angle a between an incident light beam and the emergent light beam that are on the reflector on a vertical plane has a following relationship with a vertical inclination angle β of the MEMS micromirror and a vertical swing angle co of the MEMS micromirror:

α≥ε(2β+ω), wherein

ε is an installation error factor of the reflector and the MEMS micromirror; and
each of the N laser ranging components is further configured to receive the echo light beam.
