The laser distance detector is an instrument that uses a certain parameter of the modulated laser to measure the distance to the target. According to the distance measurement method, it is divided into phase method distance detector and pulse method distance detector. The pulsed laser distance detector emits a beam or a sequence of short pulsed laser beams to the target when it is working, and the photoelectric element receives the laser light 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 distance detector detects the distance by detecting the phase difference that occurs when the emitted light and the reflected light propagate in space. The laser distance detector is light in weight, small in size, simple to operate, fast and accurate, and its error is only one-fifth to one-hundredth of other optical distance detectors. The picture on the left shows a typical phase method distance detector. And pulse method distance detector diagram.
Laser distance detectors are widely used in terrain surveying, battlefield surveying, tanks, aircrafts, ships and artillery ranging from targets, measuring the height of clouds, aircraft, missiles and satellites. It is an important technical equipment to improve the accuracy of high tanks, aircraft, ships and artillery. As the price of laser distance detectors continues to drop, the industry has gradually begun to use laser distance detectors, which can be widely used in industrial measurement and control, mines, ports and other fields.
