What Is A Laser Range Finder?
Dec 12, 2018

A laser range finder is an instrument that uses a laser to accurately measure the distance of a target. The laser range finder emits a very thin laser beam to the target during operation, and the photoelectric component receives the laser beam reflected by the target. The timer measures the time from the transmission to the reception of the laser beam, and calculates the distance from the observer to the target.


If the laser is continuously launched, the measuring range can be up to 40 kilometers, and it can be operated day and night. If the laser is pulsed, the absolute accuracy is generally low, but for long distance measurement, good relative accuracy can be achieved.


The world's first laser was first developed by the American Hughes Aircraft Company's scientist, Mehman, in 1960. The US military quickly conducted research on military laser devices on this basis. In 1961, the first military laser range finder passed the US military demonstration test, and the laser range finder quickly entered the practical complex.


The laser range finder is light in weight, small in size, simple in operation, fast and accurate, and its error is only one-fifth to one-hundredth of the other optical range finder. It is widely used in topographic survey, battlefield measurement, and tank. , aircraft, ships and artillery to the target, 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 range finder has been continuously lowered, the industry has gradually begun to use laser range finder. A number of new miniature range finder with fast measuring range, small size and reliable performance have appeared at home and abroad, which can be widely used in industrial measurement and control, mining, port and other fields.
