Abstract

Quantum imaging of an obscured object is achieved by the gated coincidence measurement of first the thermal source transverse intensity and second the measured count of scattered and reflected photons that have traversed the obscurant. Interestingly, the CCD camera is looking at the pseudo thermal source of photons not the object. The image does not exist in the mean, but only in the coincidence and has a higher image quality metric than that achieved by a camera viewing the object through the obscurant.
