What are the common problems of using
laser range finder? Let us first understand what is a laser rangefinder. As the name implies, it is an instrument used to measure distances. It is mainly used for accurate and rapid measurement of distances and heights in coal mines, roadways, working faces, and mining faces. Calculate area, volume, and more. The instrument has the characteristics of telescope, data storage, laser automatic shutdown, instrument automatic shutdown, high measurement accuracy, small size, light weight, and convenient use. It can be widely used in the environment where there are flammable, explosive and combustible gas mixtures to measure the distance of the target.
The laser rangefinder adopts the photoelectric principle and uses a non-contact method to achieve distance measurement by comparing the phase of the amplitude-modulated laser signal. The divergence angle of the laser diode is 0.6mrad, so a very high detection accuracy can be achieved. Measurement results can be output through RS232 or RS422, as well as digital output and 4-20mA analog output. The distance range corresponding to the analog output can be defined by the user, and the zero point offset of the measurement distance can be determined arbitrarily.
