Description

High accuracy engineering measurement is with laser range finder Technical Field The utility model relates to the technical field of laser rangefinders, in particular to a laser rangefinder for high-precision engineering measurement. Background The laser range finder is an instrument for measuring the distance of a target by using a certain parameter of modulated laser. According to the distance measuring method, a phase method distance measuring instrument and a pulse method distance measuring instrument are classified, wherein the pulse laser distance measuring instrument emits a beam or a sequence of short pulse laser beams to a target during operation, the photoelectric element receives the laser beams reflected by the target, the timer measures the time from the emission to the receiving of the laser beams, the distance from an observer to the target is calculated, and the phase method laser distance measuring instrument detects the distance by detecting the phase difference between the emitted light and the reflected light when the reflected light propagates in space. Through investigation, chinese patent utility model discloses a laser range finder (publication number: CN 219657873U) which comprises a laser range finder main body, wherein an adjusting device is arranged on the lower end surface of the laser range finder main body, and the adjusting device adjusts the horizontal placement of the laser range finder main body.
