Abstract

Phase-shifting digital holography can be used to artificially reconstruct both the amplitude and phase information of a complex object. We apply digital wavefront reconstruction to image encryption. The encrypted wavefront is recorded using a CCD sensor array, facilitating real time transmission of the encrypted message via traditional digital communication methods. Initial experimental results show that high security strength can be obtained with currently available devices.
