Tag: laser distance meter

Laser distance measurement is based on the same principle as radio radar. After the laser is aimed at the target and fired, its round-trip time is measured and multiplied by the speed of light to obtain the round-trip distance. Since laser has the advantages of high directionality, high monochromaticity and high power, which are crucial for measuring long distances, determining the orientation of the target, improving the signal-to-noise ratio of the receiving system, and ensuring the measurement accuracy, laser rangefinders are gaining more and more attention. Based on the laser rangefinder, LIDAR can not only measure the distance, but also the target's orientation, speed and acceleration. It has been successfully used for the ranging and tracking of artificial satellites.
