TLDR
In this article, a two-photon optical imaging experiment was performed based on the quantum nature of the signal and idler photon pairs produced in spontaneous parametric down-conversion, where an aperture placed in front of a fixed detector is illuminated by the signal beam through a convex lens.Abstract:
A two-photon optical imaging experiment was performed based on the quantum nature of the signal and idler photon pairs produced in spontaneous parametric down-conversion. An aperture placed in front of a fixed detector is illuminated by the signal beam through a convex lens. A sharp magnified image of the aperture is found in the coincidence counting rate when a mobile detector is scanned in the transverse plane of the idler beam at a specific distance in relation to the lens.read more

Effect of oceanic turbulence on the visibility of underwater ghost imaging
TL;DR: The results show that the quality of GI under the effects of oceanic turbulence is related to the intensity of turbulence and the propagation distance of light, which provides guidance for the realization of adaptive underwater optical GI over different length scales under the effect of Oceanic turbulence.
