| 摘 要： | 用双位相密钥衍射系统以解决简单三维立体信息的加密问题. 选取旋转抛物面包围的三维信息作为加密对象,用相位恢复算法设计了双位相密钥. 计算机模拟结果证实了该系统的有效性,并揭示了不同约束条件、迭代次数等对三维信息整体恢复质量所造成的影响. 研究发现,应针对实际的设计需求在算法开销与整体恢复质量之间取得平衡.

| Abstract: | 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 wo... |
