水下光通信(Underwater optical wireless communication, UOWC)是一种新型的水下通信技术,具有保密性好、可靠性高等优点,对于构建全光立体通信网络以及6G空天海地一体化全方位通信有重要的意义。分析了水下光通信相较于其他传统水下通信方式的优点,对水下光通信发展历程与进展进行了综述,对比了水下光通信两种主流光源：激光光源和LED光源。针对现阶段水下光通信面临的难题,提出了一种完善的水下光通信系统框图,并研制出相应的硬件系统,完成了水下通信调试。水下光通信是一种切实可行的新型通信方式,兼具灵活、保密、高速率等特点,在未来的6G时代中将会得到进一步的发展和应用。
Underwater optical wireless communication (UOWC) is a new type of underwater communication technology, which has the advantages of good confidentiality and high reliability. It is of great significance for the construction of all-optical three-dimensional communication network and 6G air space Haiti integrated all-round communication. This paper analyzes the advantages of underwater optical communication compared with other traditional underwater communication methods, summarizes the development history and progress of underwater optical communication, and compares two mainstream light sources of underwater optical communication: laser light source and LED light source. Aiming at the problems of underwater optical communication at present, a perfect block diagram of underwater optical communication system is proposed, the corresponding hardware system is developed, and the underwater communication debugging is completed. Underwater optical communication is a new practical communication mode, which has the characteristics of flexibility, confidentiality and high speed. It will be further developed and applied in the 6G era in the future.
