Description

technical field [0001] The invention relates to the technical field of laser ranging, in particular to a laser ranging instrument. Background technique [0002] The world's first laser was a ruby ​​laser developed successfully in 1960 by Maiman, a scientist from the Hughes Aircraft Company of the United States. The U.S. military soon launched research on military laser devices on this basis. In 1961, the first military laser range finder passed the demonstration test of the US military, and the laser range finder soon entered the practical stage. [0003] A laser range finder is an instrument that uses a certain parameter of a modulated laser to measure the distance to a target. 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 ...
