The generation of multiple vortex cones using an annular aperture array and a spatial light modulator (SLM) is studied. The direct downscale imaging of an SLM on the surface of an annular aperture enables the direct-phase modulation of the annular aperture. It is experimentally demonstrated that the direct-phase modulation of an annular aperture array can control both the topological charge and the horizontal positions of multiple vortex cones simultaneously.
研究了使用环形孔径阵列和空间光调制器（SLM）生成多个涡旋锥的方法。SLM在环形孔径表面上的直接缩微成像实现了环形孔径的直接相位调制。实验证明，环形孔径阵列的直接相位调制可以同时控制多个涡旋锥的拓扑电荷和水平位置。
