    Conclusions

    This study presents a method for achieving rapid beam alignment using image calibration at the transmitting end and a two-dimensional mirror control at the receiving end, thus, addressing the problem of long time-consuming beam alignment in traditional wireless optical communication. The image calibration coarse tracking at the transmitting end can ensure that the spot effectively covers the two-dimensional mirror, and the coupling spot coarse tracking at the receiving end can effectively suppress the beam drift caused by atmospheric turbulence; the uplink can be established simultaneously with the downlink. The non-common sight axis control avoids the inconvenience of transmitting control instructions from the receiving end to the transmitting end, and it is not necessary to use a space stable platform for the moving base, which greatly facilitates the promotion of wireless optical communication.
