What is a laser ranging sensor?

Laser ranging sensors are sensors that use laser light to accurately measure the distance to a target. The laser ranging sensor is an instrument that uses certain parameters of the modulated laser to accurately measure the distance of the target. Pulsed laser ranging sensors emit one or a series of short pulsed laser beams at a target during operation. The function of the photoelectric element is to receive the laser beam reflected from the measurement target, and the timer accurately measures the time from emission to reception of the laser beam, and calculates the measurement value. The distance from the instrument to the target. Most laser ranging sensors use a phase-based ranging method with an accuracy of 1mm and are suitable for a variety of high-precision measurement applications.

When the laser spot of the laser ranging sensor is aimed at the target and emitted, the round-trip time is measured, and then multiplied by the speed of light to obtain the round-trip distance. Radar sensor laser ranging has the advantages of strong directionality, high monochromaticity, and high power. These are very important for long-distance measurement, determining the target orientation, improving the signal-to-noise ratio of the receiving system and ensuring measurement accuracy.

Because the laser ranging sensor has the characteristics of high directivity, high monochromaticity and high power, these are very critical for long-distance measurement, determining the target azimuth angle and ensuring measurement accuracy. The laser ranging sensor device with added lidar can not only measure distance, but also measure target azimuth and moving speed.
