System modeling and optimization of Fourier holographic memory.

A new fast-Fourier-transform-based model of a page-oriented holographic data-storage system is presented. The model accounts for essential system and storage material features (e.g.

Amplitude, phase, and hybrid ternary modulation modes of a twisted-nematic liquid-crystal display at approximately 400 nm.

Applicability of a commercial twisted-nematic liquid-crystal display is examined at approximately 400 nm. Different modulation modes predicted by Jones-matrix calculus are experimentally tested. High contrast amplitude modulation with negligible loss, high contrast and low loss hybrid ternary modulation, and 1.
