Tips: What is the principle of laser rangefinder?

A laser rangefinder is an instrument that uses a certain parameter of the modulated laser to accurately measure the distance to the target. The principle of ranging can basically be attributed to measuring the time required for the light to travel to and from the target, and then calculate the distance D through the light and the atmospheric refraction coefficient n. Since it is difficult to measure time directly, it is usually to measure the phase of the continuous wave, which is called a phase-measuring rangefinder. Of course, there are also pulsed rangefinders. Usually, precise ranging requires the cooperation of a total reflection prism, and the rangefinder used for house measurement is directly measured by the reflection of a smooth wall, mainly because the distance is relatively close, and the signal strength of the reflected light is large enough. It can be known from this that it must be vertical, otherwise the return signal is too weak and the precise distance cannot be obtained.
