title: Optical image encryption based on interference of polarized light.
abstract: We proposed a novel architecture for optical image encryption based on interference between two polarized wavefronts. A polarization-selective diffractive optical element is employed to generate the desired polarized wavefronts by modulating the incident polarized light beam. The encryption algorithm for this new method is simple and does not need iterative encoding. Numerical simulation is performed to demonstrate the validity of this new proposed method.
