Editorial - Special issue on enhanced quantum imaging

Abstract

Quantum imaging is the art extending the range and quality of imaging using the full quantum properties of photons. Optical imagining has a long tradition and is imbedded in many other technologies, including medical diagnostic techniques, environmental monitoring, and technical imaging. The most obvious imaging techniques are those based on the use of an optical system, camera lens, microscope or telescope, designed to produce an image of an object and to record this intensity distribution with a camera, in the old days on film and nowadays on an array of photo-detectors. We now think of images in the form of pixels, defined by the individual detectors.
