[0002] Underwater communication technology is one of the key technologies for underwater resource development. Underwater communication technology can realize the transmission of data and information between various devices and nodes. As people's exploration of the ocean continues to deepen, the requirements for underwater wireless communication technology are getting higher and higher. Compared with traditional underwater acoustic communication, underwater visible light communication systems can be small in size, low in cost, and easy to integrate and design. In addition, the high communication rate and high modulation bandwidth of visible light communication technology can realize high-speed and low-latency data transmission over medium and short distances between underwater device nodes. Therefore, it can make up for the shortcomings of underwater acoustic communication technology and has great application prospects in ocean exploration.

[0003] Due to the constraints of seawater flow and seawater scattering, the communication performance and communication distance of underwater visible light communication are limited.
