Abstract

The rapid establishment and stable maintenance of blue-green laser communication links are the conditions for the application of underwater long-distance laser communication. In the case of platform disturbance and random disturbance of seawater channels, the dynamic adaptive Acquisition Pointing and Tracking (APT) system ensures high-precision and fast alignment of laser communication links. Aiming at the problem of communication interruption caused by the interference in underwater laser communication links, combined with the characteristics of an adjustable liquid crystal optical attenuator and photoelectric tracking system, a dynamic adaptive underwater laser communication APT control system is designed and developed in this essay. The experimental results show that the blue-green laser communication system realizes the full-duplex communication function and has engineering significance.
