In this paper, we propose a method of using double-plane phase only functions (DPPOFs) and applying Fresnel diffraction transform to achieve double-plane image reconstruction/authentication. Based on the principle of optical Fresnel diffraction, we use the double phase retrieval algorithm to encode two target images at two different reconstruction planes into DPPOFs. The simulation results show that the two target images can be successfully reconstructed ...
