AI Technical Summary
Existing technologies cannot effectively correct the coaxiality of the receiving and transmitting axes of satellite laser terminals without the aid of ground stations, and existing solutions are either inefficient or highly complex.
By receiving beacon light and signal light emitted by the laser terminal at the other end, and using the coarse tracking mirror, fine tracking mirror and advanced aiming mirror inside the laser terminal, the optical axis is circularly scanned and the offset is calculated to achieve the correction of the optical axis.
Without altering the structure of the laser terminal, coaxiality correction of the light and receiver axes was achieved, improving the efficiency of optical axis correction and enabling synchronous establishment with the optical signal, thus shortening the optical axis calibration time.
