PRINCIPLE OF RANGING
After the laser imager is started, the laser pulse with a periodic frequency of 1Hz is emitted, which reaches the measured target through the transmitting antenna. Most of the beam is absorbed or diffusely reflected by the target, while a very small part of the beam returns to the receiving antenna and converges on the detector module. The detector module samples the reflected signal and obtains the distance information of the measured target through an algorithm.
Examples of calculation:
Measurement time (one round trip) =10us
Propagation time (one way) =10us/2=5us
Ranging distance = Light speed × travel time =300000km/s×5us=1500m
RANGING CAPABILITY IN DIFFERENT VISIBITY
Atmospheric visibility has a great impact on the ranging performance of laser photometer. Please refer to Figure 2 for the ranging capability of this product in different visibility.

HUMAN EYE SAFETY
The laser rangefinder uses a laser source in the band of 1064nm. When using the laser in this band, it is necessary to avoid the outgoing beam directly into the human eye as far as possible to prevent human eye injury.
MECHICAL INTERFACE
The mechanical interface of the laser photometer consists of 3 through holes, which are fixed to the installation platform by 3 M5 screws. The dimensions of the mechanical and optical interfaces are shown in Figure 3 below.
Figure 3 shows the mechanical and optical interfaces
