摘　　要：将光学涡旋与计算全息技术相结合,提出一种高质量光学涡旋阵列的产生方法.从理论上研究了光学涡旋阵列的形成和分布特征,并模拟仿真产生涡旋光束阵列.基于面向目标的共轭对称延拓傅里叶计算全息方法编码生成光学涡旋阵列的全息图,利用单个反射式空间光调制器光电再现了与理论一致的光学涡旋阵列,并通过马赫-增德尔干涉法对生成的光学涡旋阵列进行验证.产生的高质量光学涡旋阵列提供了更复杂的结构分布和更多的可控参量,且实验光路易实现.研究结果在光学微操控、光通信等领域具有潜在应用价值.Combined the optical vortex with computer generated holography,an approach for producing optical vortex array with high quality was proposed.The formation and distribution characteristics of optical vortex array were theoretically discussed,and optical vortex array was produced by numerical simulation.The hologram of optical vortex array was generated by conjugate symmetric extension Fourier computer generated holography.Based on spatial light modulator loaded with holograms,the optical vortex arrays were reconstructed in the experiment.In order to evaluate the generated beams,Mach–Zehnder interference system was adopted.It is very simple and easy to produce the optical vortex array,which provides more complicated light distributions and controllable parameters.The research results may have a potential value in optical micromanipulation,optical communication and other fields.
