This is an era of rapid technological development, and people's lives are increasingly dependent on scientific and technological achievements. Take the laser rangefinder as an example. In the past, people used tape measure, disconnection, measurement, etc. to measure distance, but now it can be done by pressing a button on this small laser rangefinder. Moreover, laser rangefinders are more accurate and smaller than those traditional measurement methods. Lightweight and easy to carry.
Due to its wide range of uses, the development of laser rangefinders is unstoppable. The laser rangefinders on the market now include pulsed laser rangefinders and phase laser rangefinders. Although they are all used to measure distances, they have their own advantages. The pulsed laser rangefinder has a wide measurement range and poor accuracy, while the phase laser rangefinder has a small measurement range but high accuracy can reach a millimeter level. Among them, the application fields of pulsed laser ranging are becoming wider and wider, such as topographic surveying, tactical frontier ranging, missile orbit tracking, and measurement of artificial satellites, the distance from the earth to the moon, and so on. Pulsed laser ranging method uses the characteristics of laser pulse duration is very short, the energy is relatively concentrated, and the instantaneous power is very large. In the case of cooperative targets, pulsed laser ranging can reach extremely long range; if only using the measured The weak reflection signal obtained by the diffuse reflection of the pulse laser by the target can also be used for distance measurement. Therefore, the pulsed laser ranging method is widely used.
Now briefly explain the working principle of the pulsed laser rangefinder: the laser emitted by the rangefinder is reflected by the object to be measured and then received by the rangefinder. The rangefinder also records the round-trip time of the laser, the product of the speed of light and the round-trip time. Half of that is the distance between the rangefinder and the object to be measured.
The measurement accuracy of pulsed laser rangefinders is poor, and the general accuracy can only reach the level of m, so some occasions or projects with high accuracy requirements need to use phased laser rangefinders. However, for long-distance measurement, due to the wide measurement range, a measurement error of one or two meters is already considered to be very accurate.
