Correlated two-photon imaging with true thermal light
TL;DR: In this paper, the first experimental demonstration of two-photon correlated imaging with true thermal light from a hollow cathode lamp is reported, and the coherence time of the source is much shorter than that of previous experiments using random scattered light from the laser.
Journal ArticleDOI
Ghost-imaging experiment by measuring reflected photons
TL;DR: In this article, a CCD array is placed facing a chaotic light source and gated by a photon counting detector that simply counts all randomly scattered and reflected photons from an object, and a ''ghost'' image of the object is then observed in the gated CCD.
Journal ArticleDOI
Lensless ghost imaging with true thermal light.
TL;DR: Although there is no magnification, the method is suitable for all wavelengths and so may find special applications in cases where it is not possible to use lenses, such as with x rays or gamma rays.
Journal ArticleDOI
High-visibility, high-order lensless ghost imaging with thermal light
TL;DR: High-visibility Nth-order ghost imaging with thermal light has been realized by recording only the intensities in two optical paths in a lensless setup and it is shown that the visibility is dramatically enhanced as the order N increases, but longer integration times are required owing to the increased fluctuations of higher-order intensity correlation functions.
Journal ArticleDOI
Optimization of thermal ghost imaging: high-order correlations vs. background subtraction
TL;DR: It is found analytically that the CNR of the normalized high-order ghost image is inversely proportional to the square root of the number of transmitting pixels of the object, and is the same as that of conventional ghost imaging with background subtraction.
