Quantum Imaging beyond the Diffraction Limit by Optical Centroid Measurements
arXiv:0901.4817 · doi:10.1103/PhysRevLett.102.253601
Abstract
I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multiphoton absorber as the detector. Using the same non-classical states of light as those for quantum lithography, the proposed method requires only intensity measurements, followed by image post-processing, to produce the same complex image patterns as those in quantum lithography. The method is expected to be experimentally realizable using current technology.
