Holographic Encryption Applications Using Multichannel Bessel Beam

Abstract

For microwave encryption, holography offers a way to reconstitute both the intensity distribution and the phase distribution. This study presents a holographic encryption method that uses a multichannel Bessel beam as the encryption key and uses the phase distribution of special characters carrying information as the output. The two quasi-optical mirrors that make up the bulk of the system are optimized for deformation using a tweaked version of the Katsenelenbaum-Semenov algorithm. Using commercial software, we can simulate a system and get its output field for various inputs. together with high levels of security are confirmed by simulation.
