摘要
提出并展示了产生单个可调局域空心光束的一种新型元件。该元件由光罩与平凸透镜组成,结构简单,易于生产。该元件可调制平行光产生参数固定的局域空心光束,通过更换光罩可在较大范围内实现局域空心光束的尺寸调谐。从应用光学角度分析了新型元件的成像原理,推出了产生局域空心光束的参数公式。依据衍射积分理论推导出了元件后方的光场分布公式并用Matlab 进行数值模拟,使用He-Ne 激光作为光源,实验拍摄了局域空心光束的截面光强分布,实验结果与仿真模拟基本吻合。
Abstract
A novel compact optical component aimed at transforming a plane wave into a bottle beam is proposed and demonstrated. This component consists of a cover and aplano-convex lens which has the advantage of simple structure and easy production. The component can generate bottle beam with fixed parameters by modulating paralleling light and achieve the target of turning the size of bottle beam in wide range by replacing the cover. The formation mechanism of bottle beam is analyzed by geometrical optics, the relevant parameters expression is also derived. According to the diffraction integral theory, the distribution of the light field behind the element is derived and the numerical simulation is carried out with Matlab. Using He- Ne laser as light source, the cross sectional intensity distribution of bottle beam in experiment is captured.The results are basically consistent with the simulation.
