Abstract

Vortex beam (VB), which carry orbital angular momentum, offers significant potentials for high-efficiency and high-capacity data encoding. Robust propagation of VB in turbulence has garnered significant interests. However, their widespread adoption has been hindered by their sensitivity to turbulence-induced distortions, as their phase profiles are highly susceptible to distortions. In this work, we propose a steady optical vortex beam (STOVB) that integrates the properties of steady optical beams (STOB) with VB. STOVB achieves both an extended depth of focus and robust data transmission in turbulence, demonstrating a 17.6% reduction in intensity variation over time. This approach provides a promising pathway for high-resolution imaging and optical communication in challenging environments such as air, water, and other complex media.

稳定的光学涡旋光束可以在湍流中扩展聚焦深度和稳健的数据传输

具有轨道角动量的涡旋光束在高效、高容量的数据编码中具有重要的应用前景。VB在湍流中的鲁棒传播引起了人们极大的兴趣。然而，由于它们对湍流引起的畸变的敏感性，它们的广泛采用受到阻碍，因为它们的相位曲线极易受到畸变的影响。在这项工作中，我们提出了一种综合了稳态光束和涡旋光束特性的稳态光涡旋光束。STOVB在湍流中实现了更大的聚焦深度和强大的数据传输，随着时间的推移，强度变化减少了17.6%。这种方法为具有挑战性的环境（如空气、水和其他复杂介质）中的高分辨率成像和光通信提供了一条有前途的途径。

期刊介绍： Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods. Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following: -Optical Metrology- Optical Methods for 3D visualization and virtual engineering- Optical Techniques for Microsystems- Imaging, Microscopy and Adaptive Optics- Computational Imaging- Laser methods in manufacturing- Integrated optical and photonic sensors- Optics and Photonics in Life Science- Hyperspectral and spectroscopic methods- Infrared and Terahertz techniques
