We investigate the effect of turbulence on quantum ghost imaging. We use entangled photons and demonstrate that for a specific experimental configuration the effect of turbulence can be greatly diminished. By decoupling the entangled photon source from the ghost-imaging central image plane, we are able to dramatically increase the ghost-image quality. When… (More)
A new type of confocal microscope is described which makes use of intensity correlations between spatially correlated beams of light. It is shown that this apparatus leads to significantly improved transverse resolution.
We introduce two new devices, the correlation confocal and twin-photon microscopes. Like the standard two photon confocal microscope, they use spatially-correlated photon pairs to improve lateral resolution, but with the correlation enforced in different manners. Ocis codes: (180.1790) Confocal microscopy; (180.5810) Scanning microscopy; (190.4970)… (More)
We discuss an apparatus capable of producing correlated-photon "ghost" images that cancel all object-induced aberrations in a particular plane and all odd-order aberrations induced by the image-forming optics. We show that both entangled and classically correlated light sources can produce the desired spatial-aberration cancellation.
Atmospheric turbulence generally affects the resolution and visibility of an image in long-distance imaging. In a recent quantum ghost imaging experiment [P. B. Dixon et al., Phys. Rev. A 83, 051803 (2011)], it was found that the effect of the turbulence can nevertheless be mitigated under certain conditions. This paper gives a detailed theoretical analysis… (More)
