We propose an optical encryption system using circular polarization based on interferometer architecture. The phase-modulated input image, represented as orthogonal linearly polarized states by interferometer, is encrypted into circularly polarized states whose direction of the rotation is random. In the decryption we use the inverse matrix of polarization-modulation key and can recover the original polarization states.
