论文摘要
通过实验和理论上研究了轨道角动量诱导的作用在辐射极化矢量束在径向极化矢量束衍射中的表现。进行实验以提取圆极化的程度，该度圆极化与旋转角动量密度的轴上成分成正比。我们报告了分别与正阵拓扑电荷相关的左右圆形极化区域的明显分离，这让人联想到标准涡旋诱导的横向移位，尽管在衍射情况下。实验结果由模型模拟支持，一致性非常令人满意。由于不可避免的未对准问题（尤其是对于涡旋束），因此结果可用于欣赏轨道轨道相关的效果。
Manifestations of orbital angular momentum induced effects in the diffraction of a radially polarized vector beam by an off-axis tilted aperture are studied both experimentally and theoretically. Experiments were carried out to extract the degree of circular polarization, which was shown to be proportional to the on-axis component of the spin angular momentum density. We report a clear separation of the regions of dominance of the right and left circular polarizations associated with positive and negative topological charges respectively, which is reminiscent of the standard vortex-induced transverse shift, albeit in the diffraction scenario. The experimental results are supported by model simulations and the agreement is quite satisfactory. The results are useful to appreciate the orbit-orbit related effects due to unavoidable misalignment problems (especially for vortex beams).
