Optical encryption method using toroidal zone plates
ABSTRACT: We present the implementation of an optical encryption method using zone plates. The optical security system is based on a computer generated phase mask. In particular, for this proposal the selected phase mask is a toroidal zone plate. In the encryption process we use an optical processor...
