Abstract
A laser-based measurement device includes a laser transmitter; a laser receiver; an optical device configured to guide a laser beam emitted by the laser transmitter out of the laser-based measurement device and guide the laser beam reflected by an external environment in the laser receiver; and a driving device including a first magnetic member connected to the optical device and a second magnetic member. The driving device is configured to drive the optical device to vibrate through interaction between the first magnetic member and the second magnetic member, to change a guiding direction of the laser beam passing through the optical device.
