Laser ranging sensor is an instrument that uses laser to accurately measure the distance of the target. The laser ranging sensor emits a very thin laser beam to the target during operation, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the laser beam emission to the reception, and calculates the distance from the observer to the target. The laser ranging sensor is light in weight, small in size, simple in operation, fast and accurate, and its error is only one fifth to several hundredths of other optical ranging sensors.

A laser ranging sensor is an instrument that uses a laser to accurately measure the distance to a target. The laser ranging sensor emits a very thin laser beam to the target during operation, and the photoelectric element receives the laser beam reflected by the target. The timer measures the time from the laser beam emission to the reception, and calculates the distance from the observer to the target.

If the laser is emitted continuously, the measuring range can reach about 40 kilometers, and the operation can be carried out day and night. If the laser is pulsed, the absolute accuracy is generally low, but for long-distance measurement, a good relative accuracy can be achieved.

As the price of laser ranging sensors continues to drop, the industry has gradually begun to use laser ranging sensors. A number of new miniature ranging sensors have appeared at home and abroad with the advantages of fast ranging, small size and reliable performance, which can be widely used in industrial measurement and control, mines, ports and other fields.

Laser is a new technology developed in the 1960s. It is a kind of light with very pure color, highly concentrated energy and good directionality. A laser ranging sensor is an instrument that uses lasers to measure distances. How it works is simple: distance is determined by measuring the time between when the laser starts firing and when the laser bounces off the target. For example, a laser ranging sensor is used to measure the distance of the moon. If the time from the start of the laser emission to the reflection from the moon is measured as 2.56 seconds, the one-way time from the laser to the moon is equal to 1.28 seconds, and the speed of the laser is the speed of light, which is equal to 300,000 kilometers per second. Therefore, the measured distance of the Moon from the Earth is the product of the one-way time and the speed of light, or 384,000 kilometers. In order to transmit and receive laser light and time, the laser ranging sensor is composed of laser transmitter, receiver, clock frequency oscillator and distance counter.

Laser ranging sensors can also be used to track and measure artificial satellites, measure the flight height of aircraft, target and measure targets, and conduct terrain mapping and surveying.
