Research Progress of Vortex Beam Array Generation Technology
摘要
与单涡旋光束相比,涡旋光阵列具有多个相位奇点,不仅能够增大信息传输容量,还能增加捕获和观察到的微粒数量。目前在光学领域有多种涡旋光阵列的产生方法,如干涉法、泰伯效应法、光楔衍射法、模式转换法、达曼涡旋光栅法、计算全息法、空间光调制法、超材料图案法等。对这些研究方法的理论模型、实验原理、实验结果及其研究现状进行了详细介绍,并对应用前景作出展望。
Abstract
Compared with single vortex beam, vortex beam array has multiple phase singularities, which can not only increase information transmission capacity, but also increase the number of particles captured and observed. At present, there are various methods for generating vortex beam array in the field of optics, such as interferometry, Talbot effect method, optical wedge diffraction method, mode conversion method, Dammann vortex grating method, computational holography method, spatial light modulation method, and metamaterial pattern method. In this paper, the theoretical model, experimental principle, experimental results, and research status of these methods are introduced in detail, and their application prospects are presented.
