论文摘要
编码多个极化的光状态 - 矢量梁 - 提供了计量和通信方面的独特功能。但是，他们的实际应用受到缺乏以可扩展和紧凑的方式测量许多极化的方法的限制。在这里，我们在没有任何极化光学元件的情况下演示了矢量梁的极化法。我们通过多个光散射和利用监督学习来将光束极化含量映射到空间强度分布中，以进行多个极化的单发测量。该方法还使我们能够将光束分类为未知数量的极化模式，这是传统技术中缺少的功能。我们的发现为极化结构光提供了快速而紧凑的极性计，这是一种通用工具，可以从根本上影响传感，成像和计算的光学设备。
States of light encoding multiple polarizations - vector beams - offer unique capabilities in metrology and communication. However, their practical application is limited by the lack of methods for measuring many polarizations in a scalable and compact way. Here we demonstrate polarimetry of vector beams in a single shot without any polarization optics. We map the beam polarization content into a spatial intensity distribution through multiple light scattering and exploit supervised learning for single-shot measurements of multiple polarizations. The method also allows us to classify beams with an unknown number of polarization modes, a functionality missing in conventional techniques. Our findings enable a fast and compact polarimeter for polarization-structured light, a universal tool that may radically impact optical devices for sensing, imaging, and computing.
