Dr. Emad AbdulZahra Mohammed and Miss. Israa Mohammed Qasim published a paper entitled (Optical double-image cryptosystem based on a joint transform correlator in a linear canonical domain) in the Applied Optics, which is indexed in Scopus/Web of Science database. The study aims to present a novel method for optical security and cryptographic systems. In this proposal, we use a QPES in the double-image encryption and authentication method to overcome the vulnerability of the method based on the JTC and the conventional 4f-optical processor in the Fourier domain.
