what is the principle of laser rangefinder?
There are many types of measuring instruments. A rangefinder is usually used for distance measurement. Among many rangefinders, laser rangefinders are widely used. The measurement is fast and accurate, and it is widely used. However, many friends do not know how the laser rangefinder works. Let's introduce it.
In fact, the principle of the laser rangefinder is very simple. The laser rangefinder emits a very thin laser beam to the target, and the photoelectric element receives the reflected laser beam from the target. The speed of light, calculating the distance from the observer to the target.
