The phase-encoded joint transform correlator as a decoder of an optical double random phase encoding system is described. By using the phase-encoded joint transform correlator, it is possible to decode the encrypted image with the same random phase mask which was used in the encryption procedure. The decoding algorithm and optical systems are described. Computer simulations confirm the proposed decoding algorithm.
