In this paper, a novel imaging technology based on entangled photon pairs generated by spontaneous parameter down-conversion was introduced The concept of tangle optic, the process of entangled photon pair was introduced also. At the foundation of single photon imaging theory, theory of entangled photon imaging was analyzed in system, the frame diagram of imaging system based on entangled photon pairs was presented, primary error sources and factors were analyzed., At last, the superiority, technology difficulties develop trend and potential apply foreground of imaging technology based on entangled photon pairs were pointed.
