摘　　要：We focus on the study of the transferred image property in an electromagnetically induced transparency （EIT）system. In our experiment, a triple-peak image is effectively transferred trom a coupling beam to a signal beam based on the FIT effect. It is found that the transferred image intensity profile of the signal beam is the same as that of the coupling beam while not in phase. Furthermore, the propagation property of the transferred image is studied. Due to the narrowing effect, the transferred image keeps narrowing and maintains the shape well within a certain distance outside of the medium. Our experimental results are in excellent agreement with the theoretical analysis.We focus on the study of the transferred image property in an electromagnetically induced transparency （EIT）system.
