چکیده انگلیسی
An image encryption method with two-step-only quadrature phase-shifting digital holography, based on the calculated intensity of reference wave is proposed. Compared with the presented image encryption method based on phase-shifting technique, the technique need only to record two quadrature-phase holograms on CCD camera, without reference-wave intensity or object-wave intensity measurement, and the encryption keys to perform image encryption on Mach-Zehnder interferometer. When the reference-wave intensity is acquired from 2D correlation coefficient method our presented, the clear retrieved image can be obtained at high speed by certain algorithm. Its feasibility and validity were verified by a series of computer simulations.
