摘要:

我们提出了一种广义螺旋变换方案,可灵活结合阿基米德螺旋和费马螺旋等多种螺旋类型。利用等距特性,我们选择阿基米德螺旋映射并展示了其在高分辨率轨道角动量模式分选中的应用。在给定最小螺旋宽度的情况下,阿基米德螺旋映射表现出优于对数螺旋映射的性能。该广义变换方案也可在光学变换中找到多种应用,并易于扩展到与共形映射相关的其他领域。

英文摘要:

We propose a generalized spiral transformation scheme that is versatile to incorporate various types of spirals such as the Archimedean spiral and the Fermat spiral. Taking advantage of the equidistant feature, we choose the Archimedean spiral mapping and demonstrate its application in high-resolution orbital angular momentum mode sorting. Given a fixed minimum spiral width, the Archimedean spiral mapping shows superior performance over the logarithmic spiral mapping. This generalized transformation scheme may also find various applications in optical transformation and can be easily extended to other fields related to conformal mapping.
