Abstract

Using a simple optical microscope, composed of a plasmonic ultrathin condenser, an objective lens, and a camera, we show that the captured Fourier plane images can provide more information than the real plane images that would be obtained from the corresponding compound microscope. Using this simple Fourier plane imaging approach, we demonstrate that reconstructed non-scanning images of plasmonic crystals with lateral resolution beyond the optical diffraction limit can be obtained.
