The laser transmitter is mounted on a transmission platform assembly, and at least one diffuse reflector is placed around the transmission platform assembly. The laser receiving device, laser transmitter, and transmission platform assembly are all controlled by a transmission controller. The laser receiving device includes two layers of a total of 11 optical receiving units for receiving signals from spatial laser radiation sources.

[0046] In this embodiment, the laser transmitter 5 and the laser receiver are set separately, and the position and distance between them are set according to actual needs.

[0047] Among them, such as Figures 2 to 6 As shown, the transmitting platform assembly includes an optical platform 1, a transmitting platform 2 is arranged above the optical platform 1, a turntable 3 is installed on the transmitting platform 2, a main reflector 4 is installed on the turntable 3, the laser transmitter 5 is placed on the optical platform 1, the laser transmitter 5 has its light output port facing upward, and the emitted beam directly illuminates the laser lens, and the light output port of the laser lens faces the main reflector 4.

When the horizontal motor 7 starts, it drives the second-stage gear in the horizontal reduction gearbox 8 to reduce speed, causing the output shaft of the horizontal reduction gearbox 8 to rotate horizontally around the vertical axis. This, in turn, causes the reflector chamber 9 to rotate, and consequently, the main reflector 4 to rotate.
