论文摘要
在极化显微镜中观察到的某些半晶体结构形成了半晶体结构，表现出特殊的``麦芽杂交''的特征。虽然这种观察被认为是这些材料表征这些材料的一种工具，但这些模式与这些模式相关，但这些模式与这些构造相关联，这些模式与强度的旋转效果相关联，而这些效应是稳健的旋转效果，而这些效应是旋转的效果。结晶的抗坏血酸和观察在传播激光束中的光涡体以及我们的发现的形成，我们的发现表明在频率范围内使用球形。
Some anisotropic materials form semicristalline structures, called spherulites, which observed in a polarisation microscope, exhibit a characteristic ``maltese-cross"-like pattern. While this observation has been hitherto considered as a tool to characterize these materials, we show that these patterns are associated with a strong light's spin-orbit coupling induced by the spherulite structures. We experimentally demonstrate these effects using samples of crystallized ascorbic acid and observing the creation of optical vortices in transmitted laser beams, as well as the formation of inhomogeneous polarisation patterns. Our findings suggest the use of spherulites in frequency ranges, e.g. in the THz domain, where polarisation and spatial shaping of electromagnetic radiation is still a challenging task.
