摘要

散射介质严重降低了环形Airy高斯涡旋光束（RAGVB）的质量，并在轨道角动量（OAM）模式之间诱发串扰，从而影响了基于轨道角动量（OAM）的光通信系统的性能。在本研究中，我们系统地研究了散射介质对RAGVBs中OAM光谱串扰的影响。此外，我们提出了一种将光强输运方程与改进的Gerchberg-Saxton相位恢复算法（ITE-GS）相结合的校正方案，以减轻散射介质的影响，确保RAGVBs的稳定传输。这些发现在光通信、旋转传感等相关领域具有广泛的应用前景。

Crosstalk of ring Airy Gaussian vortex beams disturbed by hazy scattering media and its suppression.

The scattering medium significantly degrades the quality of the ring Airy Gaussian vortex beam (RAGVB) and induces crosstalk among orbital angular momentum (OAM) modes, thereby impairing the performance of OAM-based optical communication systems. In this study, we systematically investigate the effects of the scattering medium on the OAM spectral crosstalk in RAGVBs. Furthermore, we propose a correction scheme that combines the light intensity transport equation with a modified Gerchberg-Saxton phase retrieval algorithm (ITE-GS) to mitigate the impact of the scattering medium and ensure stable transmission of RAGVBs. These findings may have broad applications in optical communication, rotational sensing, and other related fields.
