Abstract

High density polarization holographic demonstrator system has been developed using ~2 µm thick azobenzene polyesters on reflective card form media. One possible development of the system is the introduction of phase encoding into the reference arm that provides enhanced security applications. Simulations were carried out with a custom computer program based on mathematical model of the system to generate code sets optimal in terms of code number and security level. The model is suitable also for the prediction of expected tolerances necessary before the definition of a working system. Performed experiments proved applicability of the model for possible system considerations. We also present our concept of extending thin-film holographic principle to multilayered holographic storage of increased capacity.
