Spatial-Polarization State Scrambling for Image Encryption obtained with Subwavelength Gratings

Not Accessible

Your library or personal account may give you access

Abstract

We present an optical encryption/decryption methods based on geometrical phase produced by space-variant polarization manipulation. The elements are formed by use of computer-generated space-variant subwavelength dielectric gratings.
