Analysis of a Virtual Optical Encryption Holographic System: Decrypted code using the multiple-bit virtual optical encryption holographic system based on the COMSOL Multiphysics
Peng Yang, Tomoyuki Nagase · 2019
This paper presents a new method to encrypt holographic information utilize a virtual optical device where the laser wavelength λ and focal length of the lens f are main component parts of designing encryption keys. All bits that are obtained from light diffraction of a holographic material were simulated using COMSOL Multiphysics to evaluate the accuracy of the decrypted codes.
