The structure and working principle of laser rangefinder:
The basic parts of the laser rangefinder are composed of a laser transmitter, a switch system that controls the laser transmitter, an optical receiver, a timer, a computing system, and a power supply. The laser transmitter is the original component that generates laser, and it generates and emits laser under the action of the control switch. The laser receiver is to receive the laser light reflected back by the measured target (and also receive the laser light reflected back by the non-observation target). The timer records the time from when the laser is emitted to when it is reflected back. When the laser transmitter is turned on, it prompts the timer to start. When the laser hits the reflective object and is reflected back and received by the laser receiver, the timer stops timing. The calculation system calculates the distance from the observation station to the target measuring point according to the operating time of the laser and the speed of the light.
