The laser rangefinder is an instrument that uses a certain parameter of the modulated laser to realize the distance measurement of the target. It was invented by the American Hughes Aircraft Company scientist Maiman in 1960, and began to be used in the military field in 1961. The price of rangefinders continues to drop, and laser rangefinders are gradually being used in industry. With the development of laser rangefinders, it is widely used in various fields, including terrain measurement, battlefield measurement, ranging of tanks, aircraft, ships and artillery to targets, measuring the altitude of aircraft, missiles and satellites, etc.; industrial Aspects are mainly used in industrial measurement and control, mining ports and other fields.
What is the accuracy of laser rangefinders in general.
Laser rangefinder is a kind of measuring tool, and accuracy is an important performance index. The measurement accuracy of the laser rangefinder generally refers to the specified measurement error based on the ordinary measurement environment, so is the laser rangefinder high accuracy?
There are two ways to use the laser rangefinder: the pulse method and the phase method. The laser rangefinder with pulse emission generally has low absolute accuracy, but it can achieve good relative accuracy when used in long-distance measurement; phase test laser rangefinder The accuracy of the instrument can reach t1 mm. It should be noted that the error in the accuracy of the laser rangefinder is not proportional to the measured distance, and it is the same over the entire distance, but if the distance is too long, the error will increase by 40.5mm/100m.
