Abstract

Realization of full-link communication in the atmosphere and the water is a crucial area of research, it provides the pace of development of new communications technologies and the impact on the future integration of air, space, and sea. In this paper, we examine the distribution characteristics of the orbital angular momentum of Laguerre–Gaussian (LG) vortex beams in atmospheric and oceanic turbulence, derive analytical expressions for the spiral spectrum of LG vortex beams, and analyze the effects of the wavelengths, transmission paths, and beam intensity on the spectrum within turbulent environments. The findings show that long-wavelength LG vortex beams perform better in turbulent conditions. Blue-green LG vortex beams exhibit significantly enhanced performance in downlink atmospheric transmission compared to uplink transmission. Additionally, greater intensities of atmospheric and oceanic turbulence lead to a more pronounced extension of the spiral spectrum. Oceanic turbulence exerts a greater influence on blue-green LG vortex beams compared to atmospheric turbulence. This paper presents the theoretical foundation for accomplishing two-way blue-green LG vortex beam transmission between the ocean and the atmosphere.

拉盖尔-高斯涡旋光束在大气和海洋湍流中的轨道角动量输运特性

实现大气和水的全链路通信是一个至关重要的研究领域，它提供了新的通信技术的发展速度和对未来空、空、海一体化的影响。本文研究了大气和海洋湍流中Laguerre-Gaussian （LG）涡旋光束的轨道角动量分布特征，推导了Laguerre-Gaussian （LG）涡旋光束螺旋光谱的解析表达式，并分析了湍流环境中波长、传输路径和光束强度对光谱的影响。研究结果表明，长波长LG涡旋光束在湍流条件下表现更好。蓝绿LG涡旋光束在下行大气传输中表现出比上行传输显著增强的性能。此外，更强的大气和海洋湍流导致螺旋谱的扩展更为明显。与大气湍流相比，海洋湍流对蓝绿LG涡旋光束的影响更大。本文提出了实现海洋与大气之间蓝绿LG涡旋光束双向传输的理论基础。
