Laser-based measurement device and movable platform

摘要

A laser-based measurement device includes a motor comprising a hollow shaft. The laser-based measurement device also includes a laser transmitter disposed in the hollow shaft. The laser-based measurement device also includes an optical device disposed at the motor. The motor is configured to drive the optical device to rotate. The optical device is configured to guide a laser beam transmitted by the laser transmitter out of the hollow shaft, or to guide the laser beam reflected by an external environment into the hollow shaft.
