We present a new super resolution imaging method, Localized Plasmon assisted Structured Illumination Microscopy (LPSIM). Using an array of localized plasmonic antennas, LPSIM provides dynamically tunable near-field excitations which result in finely structured illumination patterns, independent of any propagating surface plasmon dispersion limitations. Antenna geometry alone limits the illumination pattern feature sizes, enabling the collection of a far-field image resolved far beyond the diffraction limit. This approach allows a wide field of view and the capacity for a high frame-rate. Recovered images for various classes of objects are presented, demonstrating significant resolution improvement over existing methods.
