A new super resolution imaging method, i.e. Localized Plasmon assisted Structured Illumination Microscopy (LPSIM), is proposed. LPSIM uses an array of localized plasmonic antennas to provide dynamically tunable near-field excitations resulting in finely structured illumination patterns, independent of any propagating surface plasmon dispersion limitations. The illumination pattern feature sizes are limited only by the antenna geometry, and a far-field image resolved far beyond the diffraction limit is obtained. This approach maintains a wide field of view and the capacity for a high frame-rate. The recovered images for various classes of objects are presented, demonstrating a significant resolution improvement over existing methods.
提出了一种新的超分辨率成像方法，即局域等离子体辅助结构光照明显微镜（LPSIM）。LPSIM 使用局域等离子体天线阵列提供动态可调谐近场激发，从而产生精细结构的照明图案，不受任何传播表面等离子体色散限制。照明图案特征尺寸仅受天线几何形状的限制，可以获得远远超过衍射极限的远场图像。这种方法保持了宽视场和高帧率的能力。针对各种类别的物体展示了恢复的图像，证明了与现有方法相比分辨率有显著提高。
