| 摘 要： | 水下无线光通信(UOWC)具有保密性好、容量大、传输速度快等优点,可应用于水下信息传输、资源勘查等领域,通信链路的快速建立和持续稳定是水下无线光通信实际应用的基本条件。在平台扰动和海水信道杂质干扰的条件下,如何实现远距离的快速对准是水下无线光通信必须解决的问题。针对水下无线光通信过程中系统发射端和接收端之间的链路由于干扰问题引起底层平台不断移动而无法对准的问题,搭建了一个基于激光二极管(LD)的水下无线光自动对准系统,该系统具有自动对准控制的特点,即系统在底层平台移动的情况下,依然可以实现链路的对准。

| Abstract: | Underwater optical wireless communication has the advantages of good confidentiality,large capacity and fast transmission speed,which can be used in underwater information transmission,resource exploration and other fields.The rapid establishment and continuous stability of communication links are the basic conditions for the practical application of underwater optical wireless communication.Under the condition of platform disturbance and sea water channel impurity interference,how to realize long-distance fast alignment is a problem that must be solved in underwater optical wireless communication.In this paper,aiming at the problem that the link between the transmitter and receiver of underwater wireless optical communication system cannot be aligned due to the interference of underlying platform,an underwater wireless optical automatic alignment system based on laser diode is built.The system has the characteristics of automatic alignment control,that is,the system can still realize the link when the underlying platform is moving alignment. |
