液晶空间光调制器模拟艾里光束在湍流中的漂移
Drift Behavior of Airy Beams in Turbulence Simulated by Using a Liquid Crystal Spatial Light Modulator
摘要
提出了一种多相位叠加的方法来模拟艾里光束在湍流大气中传输时的光斑质心漂移。通过将由Kolmogorov功率谱模型生成的随机相位屏与艾里立方相位图样叠加生成的联合相位膜片加载到空间光调制器,模拟了湍流对艾里光束的影响。通过将艾里光束和高斯光束进行比较,证实了艾里光束在湍流中传输时受扰动漂移量小于高斯光束。因此,利用艾里光束作为信息载体在远距离传输时具有很好的抗干扰能力。
Abstract
A method of superimposing multiple phase patterns in spatial light modulator to simulate the drift behavior of Airy beams in turbulence is proposed. Random phase screens which are generated by the Kolmogorov power spectrum model are superimposed with cubic phase patterns of Airy beams, and then a combined phase mask is generated. The combined phase mask is loaded into the spatial light modulator to simulate Airy beams in turbulence. Through comparing the drifts of Airy beams and related Gaussian beams, it is found that the drift distances of Airy beams are less than that of related Gaussian beams. Therefore, Airy beams as information carriers have a good anti-jamming capability in remote transmissions.
