... Before introducing the concept of ghost imaging, we briefly review the physics of classical optical imaging. Assuming an object that is either self-luminous or externally illuminated, imagining ... imaging, in certain aspects, exhibit a similar point-to-point imaging-forming function as that of classical except the ghost image is reproducible only in the joint-detection between two...
