Background

In building surveying, a laser distance meter is widely used for measuring distance. A laser rangefinder is an instrument that uses a parameter of modulated laser light to achieve a distance measurement to a target. The measuring range of the laser range finder is 3.5-5000 meters. The pulse laser distance meter emits a pulse laser beam or a series of short pulse laser beams to a target when in work, the laser beam reflected by the target is received by a photoelectric element, and a timer measures the time from the emission to the reception of the laser beam and calculates the distance from an observer to the target. The phase-method laser range finder detects a distance by detecting a phase difference occurring when emitted light and reflected light propagate in a space. The laser range finder has the advantages of light weight, small volume, simple operation, high speed and accuracy and wide application.
