[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to measure the distance to a target. The measurement range of a laser rangefinder is 3.5 to 5000 meters. According to the distance measurement method, it is divided into a phase rangefinder and a pulse rangefinder. A pulse laser rangefinder emits a beam or a series of short pulsed laser beams to the target when working. The laser beam reflected by the target is received by a photoelectric element. The timer measures the time from the emission to the reception of the laser beam, and calculates the distance from the observer to the target.
