Ghost Imaging Using Optical Correlations

Ghost Imaging Using Optical Correlations
Thomas Gregory, Miles J. Padgett, Paul-Antoine Moreau, Ermes Toninelli
Ghost imaging uses optical correlations to enable an alternative and intriguing image acquisition technique: even though information from either one of the detectors used for the acquisition does not yield an image, an image can be obtained by harnessing the optical correlations. This Review describes a variety of both quantum and classical ghost imaging techniques, and seeks to point out where these techniques may have practical applications.
