Journal ArticleDOI
Ghost imaging with thermal light: comparing entanglement and classical correlation
TL;DR: In this paper, a scheme for coherent imaging that exploits the classical correlation of two beams obtained by splitting incoherent thermal radiation is considered, and a precise formal analogy is pointed out.
Journal ArticleDOI
High-Resolution Ghost Image and Ghost Diffraction Experiments with Thermal Light
Federico Ferri,Davide Magatti,Alessandra Gatti,Morten Bache,Enrico Brambilla,Luigi A. Lugiato +5 more
TL;DR: The product of spatial resolutions of the ghost image and ghost diffraction experiments is shown to overcome a limit which seemed to be achievable only with entangled photons.
Journal ArticleDOI
Differential ghost imaging.
TL;DR: A new technique, differential ghost imaging (DGI), which dramatically enhances the signal-to-noise ratio (SNR) of imaging methods based on spatially correlated beams and allows for the first time, to the authors' knowledge, the imaging of weakly absorbing objects.
Journal ArticleDOI
Correlated imaging, quantum and classical
TL;DR: In this paper, the authors analytically show that it is possible to perform coherent imaging by using the classical correlation of two beams obtained by splitting incoherent thermal radiation, and a formal analogy is demonstrated between two such correlated beams and two entangled beams produced by parametric down-conversion.
Journal ArticleDOI
Quantum Imaging
TL;DR: A brief overview of the newly born field of quantum imaging, and some concepts that lie at the root of this field can be found in this article, where the authors provide a discussion of some of the most important concepts in this field.
