摘　　要：本文从理论和实验上系统研究了利用半波片实现高阶邦加球上柱矢量光束变换的方法.通过琼斯矩阵的方法理论分析得出变换前后柱矢量光束在高阶邦加球上两个对应点的纬度相反,经度随半波片的光轴方向角的不同而改变.最后,基于空间光调制器搭建了一套柱矢量光束产生及其变换系统,实验结果证明了这种方法的可行性.A conversion approach for cylindrical vector beams on the high-order Poincare sphere based on half-wave plate is studied theoretically and experimentally in this paper. The theoretical analysis using the Jones matrix method shows that the latitudes of two corresponding points produced by the cylindrical vector beams on the high-order Poincare sphere before and after conversion are situated oppositely, and the longitudes are changed with different azimuth angles of the half-wave plate. Finally, an experimental system for the generation and conversion of the cylindrical vector beams is established with the spatial light modulator, and the experimental results demonstrate the feasibility of this approach.
