论文摘要
本文研究了使用Michelson干涉仪对光学涡流的自我参考干涉法。发现光学涡度的拓扑电荷（TC）的检测受到某些物理条件的限制。我们通过理论分析，数值模拟和实验结果介绍了这些条件。对于不同的参数，最大可检测的TC是不同的，这有助于在实际应用中测量TC。在受约束条件允许的范围内，我们还通过更改米歇尔森干涉仪的一镜的倾斜角来研究使用双向光学涡流的干扰模式的检测。
Self-reference interferometry of optical vortices using a Michelson interferometer is investigated in this paper. It is found that the detection of topological charge (TC) for the optical vortices is constrained by some physical conditions. We present these conditions through the theoretical analyses, numerical simulation and experimental results. For different parameters, the maximal detectable TCs are different, which is helpful for the measurement of TC in the practical application. Within the range allowed by the constrained conditions, we also study the detection of TC using the interference pattern of two-way optical vortex by changing the inclined angle of one mirror of the Michelson interferometer.
