Photonic spin-orbit interactions (PSOIs) in nanostructures have attracted much interest in nanophotonics, which provide a new paradigm to enhance light-matter interactions and engineer the wavefronts of light on demand at the nanoscale. Many striking phenomena and functionalities, such as the photonic (quantum) spin-Hall effect and the spin-vortex conversion, have been demonstrated. Besides their underlying physics and manifestations, the experimental probing and imaging of PSOIs are also of great importance and highly demanded in not only the fundamental research but also the development of emerging PSOI technologies. Hence, in this review, the state-of-the-art studies on the experimental observations and detections of PSOIs are systematically reviewed, including both the far-field and near-field methods. The respective advantages and difficulties of each method are stated and analyzed. The perspectives in probing PSOIs are also discussed.

纳米结构中光子自旋轨道相互作用的探测和成像

纳米结构中的光子自旋轨道相互作用 (PSOI) 引起了纳米光子学的极大兴趣，纳米光子学提供了一种新的范式来增强光-物质相互作用并在纳米尺度上按需设计光的波前。已经证明了许多引人注目的现象和功能，例如光子（量子）自旋霍尔效应和自旋涡旋转换。除了潜在的物理和表现形式外，PSOI 的实验探测和成像不仅在基础研究中而且在新兴 PSOI 技术的发展中也具有重要意义和需求。因此，在这篇综述中，系统地回顾了关于 PSOI 实验观察和检测的最新研究，包括远场和近场方法。阐述并分析了每种方法各自的优缺点。还讨论了探索 PSOI 的观点。
