Adaptive underwater wireless laser communication terminal

In this paper, we design an adaptive underwater wireless laser communication terminal which contains optical unit, acquisition tracking and pointing (ATP) unit, and communication unit. This kind of architecture could achieve automatics alignment, and solve the contradiction of signal receiving due to the saturation of detector power at close range and insufficient power at long range. Besides, the communication rate in this design could be adjusted according to the channel conditions. The communication rate can support 100Mbps at most, and the distance can reach up to 200 meters based on the design.
