Both radially polarized and azimuthally polarized beams can be decomposed into linear combinations of circularly polarized vortex beams having opposite vortex charges. We show experimental evidence for this decomposition using a specially designed vortex sensing diffraction grating that generates multiple vortex patterns having different senses of circularly polarization in the different diffracted orders. When this grating is illuminated with a radially or azimuthally polarized beam, the grating separates the components into different diffracted orders. Experimental results are shown.
径向偏振光束和角向偏振光束都可以分解为具有相反涡旋电荷的圆偏振涡旋光束的线性组合。我们使用一种专门设计的涡旋传感衍射光栅展示了这种分解的实验证据，该光栅在不同衍射级中产生具有不同圆偏振方向的多个涡旋图案。当用径向或角向偏振光束照射该光栅时，光栅会将这些分量分离到不同的衍射级中。展示了实验结果。
