Optical Image Encryption Using a Nonlinear Joint Transform Correlator and the Collins Diffraction Transform
The Collins diffraction transform (CDT) describes the optical wave diffraction from the generic paraxial optical system. The CDT has as special cases the diffraction domains given by the Fourier, Fresnel and fractional Fourier transforms. In this paper, we propose to describe the optical double rand...
