A laser range finder is a device for accurately measuring a distance to a target by using laser light (also referred to as laser range finding). When the laser distance measuring instrument works, a thin laser beam is emitted to a target, the photoelectric element receives the laser beam reflected by the target, the timer measures the time from emitting to receiving of the laser beam, and the distance from an observer to the target is calculated.
The laser range finder has light weight, small volume, simple operation, high speed and accuracy, and the error is only one fifth to one hundred times of that of other optical range finders, so the laser range finder is widely used for measuring the distance of a target by a terrain, a battlefield, a tank, an airplane, a naval vessel and a gun, and measuring a cloud layer, an airplane, a missile and the like. The device is important technical equipment for improving the precision of tanks, airplanes, naval vessels and artillery.
As the price of laser rangefinders is continuously decreasing, the industry is also gradually beginning to use laser rangefinders.
