- W2058698081 abstract "Data security techniques based on optical theories and methods have been proposed and widely developed in recent years.Compared with conventional mathematical encryption methods optical security system provides higher processing speed,more information volume, more encryption free-degree as well as its multi-dimension and parallel processing abilities. Inthis paper we proposed a novel architecture for optical image encryption with polarization-selective diffractive opticalelement (PDOE) based on interference theory. A target image is firstly encoded into two phase-only distributions andthen these phase distributions are encrypted into the etched surface-relief pattern of a single PDOE mask. In the processof optical image decryption, when the working wavelength and the system configuration are correct, the PDOE maskwith the encoded information for the target image can generate two desired polarized wavefronts by modulating theincident light beam. These two wavefronts interfere and then generate the decrypted image. The encoding algorithm togenerate the phase-only distributions is simple and it does not need iterative process. The optical realization for imagedecryption also has the advantages of easier installation and collimation since all the optical elements are in a sameoptical axis. The employment of the PDOE mask in this optical security system will highly increase the informationsecurity and still maintain the parameter sensitivity in an acceptable region. Numerical simulation is performed todemonstrate the validity of this new proposed method." @default.
