摘要

摘要: 在清澈海水中，透射窗口在蓝绿光波段，蓝光在海水中具有很好的传输特性。为了满足深海观测网络及平台间的高速率、大容量的通信需求，本文提出了一种水下无线可见光通信系统。该系统采用470 nm LED阵列拼接结构，增大束散角，并且提出采用菲涅尔透镜作为光学天线，实现大视场接收。在20 m的水下通信距离下，成功实现了5 Mbit/s通信速率，误码率低至10⁻⁶的可靠通信，并完整地组装出了工程样机，为后续的水下动态激光通信系统奠定了基础。

Abstract: In pure seawater, the transmission window is in the blue-green light band, and blue light has good transmission characteristics. This paper proposes an underwater wireless optical communication system that uses a 470 nm LED array stitching structure, increasing the diverging angle. At the same time, we use Fresnel lens as the optical antenna realizing the wide field of view receiving. At an underwater distance of 20 m, this system could successfully achieve reliable communication at a rate of 5 Mbit/s (data rate) and a BER of 10⁻⁶, which lays a foundation for subsequent underwater dynamic laser communication systems.
