Resumen:
A multiplexing of encrypted images using an aperture arrangement on an optical system is proposed. In addition to the classical double-random phase mask procedure; this aperture arrangement introduces a parallel channeled structured encryption key that increases the robustness of the method. Based on this approach the sequential encryption and decryption of multiple input objects is achieved by using the different single channels of the aperture pupil arrangement. Numerical simulations that verified our proposed technique are presented.
