Abstract:

In this work, we propose a new sensitive polarization optical security system. This system takes advantage of the unique and interesting properties of polarization holograms, which can encode polarized complex fields. The system is controlled by an interface, which has three defined parameters and a target image. These parameters are compared with the parameters obtained of the PH Fourier diffraction intensity pattern and recovered field. We present experimental results to probe the effectiveness of the system.
