Paper Abstract

A novel architecture for the double random phase encoding optical encryption system using a joint transform correlator is proposed. In the proposed method, the joint power spectrum of the image to be encrypted and the key code is recorded as the encrypted power spectrum. Owing to the joint transform architecture, the alignment of the image and the key code is robust. Computer simulations using a computer generated hologram is presented to confirm our proposed system.
