Laser rangefinder

Laser rangefinder

Laser rangefinder is an instrument that uses laser to accurately measure the distance of a target (also known as laser rangefinder). The laser rangefinder emits a very thin laser beam to the target when it is working, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from emission to reception of the laser beam, and calculates the distance from the observer to the target.
