Optics beyond the diffraction limit
In this lecture, we introduce the basic concepts of near-field optics using two different points of view: the plane-wave angular spectrum and the electric-dipole radiation. The first approach leads naturally to the diffraction limit and to the concepts of evanescent waves and near field. The second approach shows that the basic laws of electromagnetic radiation also lead to the classical resolu...
متن کاملQuantum imaging beyond the diffraction limit by optical centroid measurements.
I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multiphoton absorber or coincidence detection. Using the same nonclassical states of light as those for quantum lithography, the proposed method requires only optical intensity measurements, followed by image postprocessing, to produce the same complex quant...
متن کاملChemical imaging beyond the diffraction limit using photothermal induced resonance microscopy
Photothermal induced resonance recently attracted great interest for enabling chemical identification and imaging with nanoscale resolution. Here, the PTIR working principles are reviewed along with the main results from a recent publication aimed at assessing the PTIR lateral resolution, sensitivity and linearity. For this purpose nanopatterned polymer samples were fabricated using electron be...
متن کاملOptical Hyperlens: Far-field imaging beyond the diffraction limit.
We propose an approach to far-field optical imaging beyond the diffraction limit. The proposed system allows image magnification, is robust with respect to material losses and can be fabricated by adapting existing metamaterial technologies in a cylindrical geometry.
