The correlated imaging is an interesting topic.Whether second correlated imaging is a pure quantum effect or classical effect is still implicit.One phenomenon of quantum theory or classical theory,which is an interesting topic.This paper analyses three correlated imaging schemes together.The first two schemes can be achieved by two-photon which is classical correlated or quantum entangled and the third one can only be achieved by entangled two-photon.Through the comparison of these schemes,we find that enta...

0引言关联成像(correlated im aging)又称双光子成像(two-photon im aging)或“鬼”成像(ghostim aging),是一种利用双光子符合探测恢复待测物体空间信息的一种新型成像技术,近年来由于其奇特的非局域性质和可以突破衍射极限等性质受到人们的关注,但是很多涉及其物理本质的问题
