Related introduction of laser range finder
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 range finder is 3.5~5000 meters.
According to the distance measuring method, it is divided into phase method range finder and pulse method range finder. The pulse laser range finder emits a beam or a series of short pulse laser beams to the target during operation, and the photoelectric element receives the laser reflected by the target. The timer measures the time from launch 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 it propagates in space. The laser range finder is light in weight, small in size, easy to operate, fast and accurate, and its error is only one fifth to one hundredth of that of other optical range finders. The picture on the right is a typical phase method range finder and pulse method rangefinder diagram.
