Abstract :
A method of position multiplexing based on modified Gerchberg-Saxton algorithm and cascaded phase modulation scheme in Fresnel-transform domain is proposed in multiple-image-encryption framework. Simulation results show that crosstalk between multiplexed images has been significantly reduced.
