We introduce for the first time, to the best of our knowledge, a three-dimensional experimental joint transform correlator (JTC) cryptosystem allowing the encryption of information for any 3D object, and as an additional novel feature, a second 3D object plays the role of the encoding key. While the JTC architecture is normally used to process 2D data, in this work, we envisage a technique that allows the use of this architecture to protect 3D data. The encrypted object information is contained in the joint power spectrum. We register the key object as a digital off-axis Fourier hologram. The encryption procedure is done optically, while the decryption is carried out by means of a virtual optical system, allowing for flexible implementation of the proposal. We present experimental results to demonstrate the validity and feasibility of the method.
据我们所知，我们首次引入了一种三维实验联合变换相关器（JTC）密码系统，该系统允许对任何三维物体的信息进行加密，并且作为一个额外的新颖特性，第二个三维物体充当编码密钥。虽然JTC架构通常用于处理二维数据，但在这项工作中，我们设想了一种技术，该技术允许使用此架构来保护三维数据。加密的物体信息包含在联合功率谱中。我们将密钥物体注册为数字离轴傅里叶全息图。加密过程通过光学方式完成，而解密则通过虚拟光学系统进行，从而使该方案能够灵活实现。我们展示了实验结果以证明该方法的有效性和可行性。
