摘　　要：为了分析水下无线光通信技术在海洋湍流中的传输行为,基于水下非视距(NLOS)传输模型、水下信道模型和相关实验,对水下无线光通信技术进行了全面总结,并分析了蓝绿光在3种不同NLOS传输模型下的传输特性。结合先前的实验结果,阐述了光在水下传输过程中吸收散射及湍流效应对水下折射率结构常数和概率分布的影响机理。同时,对水下光通信实验进行了总结,通过研制的光学系统验证了不同传输速率和不同距离下的水下光通信性能,并对水下无线光通信未来的发展方向进行了展望。To analyze the transmission behavior of underwater wireless optical communication technology in ocean turbulence,a comprehensive summary of underwater wireless optical communication technology is conducted based on the non-line-of-sight(NLOS)transmission model,underwater channel model,and related experiments.The transmission characteristics of blue and green light in three different NLOS transmission models are analyzed.Combining the previous experimental results,the mechanism by which light absorption,scattering,and turbulence effects affect the underwater refractive index structure constant and probability distribution is elucidated.At the same time,the underwater optical communication experiment is summarized,and the underwater optical communication performance at different transmission rates and distances is verified by the optical system developed.The future development direction of underwater wireless optical communication is also prospected.
