Abstract

Two-photon quantum imaging has so far demonstrated two peculiar features: (1) reproducing nonlocal images in "ghost" imaging type experiments and (2) improving imaging spatial resolution beyond the classical limit in quantum lithography type measurements. This article reports an experimental study on non-degenerate, two-color, biphoton ghost imaging which reproduced a nonlocal ghost image and simultaneously enhanced the angular resolving power of imaging by means of a greater field of view or by means of a greater imaging amplification compared with that of classical imaging.
