A laser rangefinder is an instrument that uses a certain parameter of the modulated laser to accurately measure the distance to the target. The pulsed laser rangefinder shoots a beam or a series of short-lived pulsed laser beams to the target during operation, and the photoelectric element receives the laser beam reflected by the target. The distance from the instrument to the target.
When the power of the emitted laser beam is sufficient, the measuring range can reach about 40 kilometers or even farther. The laser rangefinder can work day and night, but when there are substances with high laser absorption rate in the space, the distance and accuracy of the distance measurement will decrease.
It is a kind of light with very pure color, highly concentrated energy and good directionality. A laser rangefinder is an instrument that uses laser light 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 rangefinder is used to measure the distance to the moon. If the time from the start of the laser emission to the reflection from the moon is determined to be 2.56 seconds, the one-way time of the laser emission 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 rangefinder is composed of laser transmitter, receiver, clock frequency oscillator and distance counter.
The laser rangefinder can also be used to track and measure the distance of artificial satellites, measure the flight height of the aircraft, target and measure the distance, and conduct terrain mapping and surveying.
