In this Letter, we present an original method to extract the optical properties of surface plasmon polaritons (SPPs) on silver surfaces. A two Young's slit experiment combined with a leakage radiation microscope has been built. By correlating both imagery and coherence measurements on the same area, we are able to address the evolution of the SPP spatial coherence along its propagation. The proposed method could also be useful to explore the properties of complex plasmonic systems.
在这封信件中，我们提出了一种提取银表面表面等离激元（SPP）光学性质的原始方法。我们构建了一个结合了两个杨氏狭缝实验和一个泄漏辐射显微镜的实验系统。通过对同一区域的图像和相干性测量进行相关，我们能够研究 SPP 沿其传播的空间相干性的演变。所提出的方法也可用于探索复杂等离激元系统的特性。
