We propose a Fourier-plane encryption technique based on a joint transform correlator (JTC). The technique is based on removing the effect of phase terms in JTC and the auto-correlation terms contribute to reconstructing the original image. Computer simulations and optical experiments show the proposed method is very useful for JTC architecture.
