The laser rangefinder is an instrument that uses a certain parameter of the modulated laser to measure the distance to the target. The measuring range of the laser rangefinder is 3.55000 meters.
According to the ranging method, it is divided into phase method rangefinder and pulse method rangefinder. Pulsed laser rangefinder shoots a beam or a series of short-lived pulsed laser beams to the target during operation, and the photoelectric element receives the laser 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. The phase method laser rangefinder detects the distance by detecting the phase difference between the emitted light and the reflected light when they propagate in space. The laser rangefinder is light in weight, small in size, simple in operation, fast and accurate, and its error is only one fifth to several hundredths of other optical rangefinders.
