In this Letter, we describe spatially switched surface plasmon microscopy (ssSPM) based on two-channel momentum sampling. The performance evaluated with periodic nanowires in comparison with conventional SPM and bright-field microscopy shows that the resolution of ssSPM is enhanced by almost 15 times over conventional SPM. ssSPM provides an extremely simple way to attain diffraction limit in SPM and to go beyond for super-resolution in label-free microscopy techniques.
在本信函中，我们描述了基于双通道动量采样的空间切换表面等离子体显微镜（ssSPM）。与传统表面等离子体显微镜（SPM）和明场显微镜相比，使用周期性纳米线对其性能进行评估，结果表明，ssSPM的分辨率比传统SPM提高了近15倍。ssSPM提供了一种极其简单的方法，可在SPM中达到衍射极限，并在无标记显微镜技术中实现超分辨率。
