Distortions in pixel-matched holographic data storage due to lateral dimensional change of photopolymer storage media

Abstract

Dimensional changes in polymerizable storage materials during exposure are a source of pixel misregistration in digital holographic storage. Lateral shrinkage or expansion of photopolymer recording materials can be deduced from quantitative measurement of the shift and the magnification errors of reconstructed holograms. © 2000 Optical Society of America.
