In this study, the digital optical phase conjugation method using cameras and spatial light modulators was employed to correct wavefront distortions over a 30 m distance. In the experiment, the system exhibited a delay of 12 ± 3 ms from camera exposure to phase-conjugated light (PCL) generation. The method was tested for its ability to track moving targets. By shifting the target at regular intervals, PCL tracked the target with a movement error of 1.9%, exhibiting a linear response. It compensated for artificial atmospheric disturbances, reducing beam fluctuation by 76% compared with non-PCL. This approach shows great potential for achieving stable optical transmission under real-world conditions.
