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.
We show that a recently discussed apparatus for aberration-canceled interferometry may be modified to perform correlated-photon imaging in the so-called “ghost” imaging configuration. For objects in the vicinity of a particular plane, the images are free of object-induced phase distortions. This apparatus has the distinctive feature that it may be used to superimpose images of two objects in a manner that could lead to useful effects and applications. We show that the apparatus works using either quantum-entangled or classically correlated light sources.
Phase distortions, or aberrations, can negatively influence the performance of an optical imaging system. Through the use of position-momentum entangled photons, we nonlocally correct for aberrations in one photon’s optical path by intentionally introducing the complementary aberrations in the optical path of the other photon. In particular, we demonstrate the simultaneous nonlocal cancellation of aberrations that are of both even and odd order in the photons’ transverse degrees of freedom. We also demonstrate a potential application of this technique by nonlocally canceling the effect of defocus in a quantum imaging experiment and thereby recover the original spatial resolution.
