CCD阵列面对混沌光源放置，并由光子计数探测器门控，光子计数探测器简单地计数来自物体的所有随机散射和反射光子。然后在选通CCD中观察到物体的“重影”图像。与所有已发表的鬼影成像实验不同，该装置从物体的散射光和反射光中捕获鬼影，而不是透射光。这个新特性不仅对实际应用有用，而且从根本上也很重要。它进一步探讨了热光鬼像的非经典干涉性质。
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. A "ghost" image of the object is then observed in the gated CCD. Differing from all published ghost-imaging experiments, this setup captures ghosts from scattered and reflected light of an object, instead of the transmitted ones. This new feature is not only useful for practical applications, but is also important fundamentally. It further explores the nonclassical interference nature of thermal light ghost imaging.
