Optical Encryption System based on Circular Polarization and Interferometer
초록
We proposed an optical encryption system using circular polarization based on interferometer. The phase modulated input image, represented as orthogonal linearly polarized states respectively, is encrypted into circularly polarized states using polarization modulated masks. In the decryption we use the inverse matrix of polarization modulation mask and can recover the original polarization states.
