The double diffractive optical elements system is proposed to encrypt the simple three-dimensional object. The three-dimensional information encircled with rotary parabolic surface is chosen as the object and the double-phase keys are designed by the phase retrieval algorithm. The computer simulations verify the effectiveness of the proposed system, and reveal how the different constrain conditions and the iteration number influence the entire recovered quality of the three-dimensional information. It is worth to consider the trade-off between the algorithm consumption and the entire recovered quality based on the requirements in applications.
