Description

Technical Field

[0001] The utility model relates to the technical field of laser ranging module installation, and more specifically to a laser ranging module positioning device. Background Technique

[0002] A laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to a target. According to the ranging method, it is divided into a phase method rangefinder and a pulse method rangefinder. The pulsed laser rangefinder emits a beam or a series of short pulsed laser beams towards the target during operation. The photoelectric element receives the laser beam reflected by the target, and the timer measures the time from the emission to the reception of the laser beam to calculate the distance from the observer to the target. The phase method laser rangefinder detects the distance by detecting the phase difference that occurs when the emitted light and the reflected light propagate in space. When installing the laser ranging module, it is necessary to adjust and position the module to avoid external objects blocking the laser.
