The rangefinder is an instrument used for distance measurement, designed according to the principles of optics, acoustics and electromagnetic waves. A rangefinder is a dead reckoning instrument used to measure the distance to a target and perform dead reckoning. There are many forms of rangefinders, usually a long cylinder, composed of an objective lens, an eyepiece, and a rangefinder knob, used to measure the target distance. The laser rangefinder is an instrument that uses laser to accurately measure the distance of the target. When the laser range finder is working, it emits a very thin laser beam to the target, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the launch to the reception of the laser beam, and calculates the distance from the observer to the target. Laser range finder is currently the most widely used range finder, and laser range finder can be classified into handheld laser range finder (measurement distance 0-300 meters), telescope laser range finder (measurement distance 500-3000 meters) .
