Abstract

A major barrier to the practical use of holographic memories is deterioration of reconstructed signals due to shrinkage of the medium. It is reported that a photopolymer medium shrinks mainly in the thickness direction during recording or as a result of variations in ambient temperature, and the optimal reconstruction angle shifts and deteriorates. To avoid the influence of medium shrinkage, we propose co-axial, dual-reference-beam recording and reconstruction. The recording and reconstruction characteristics of this method were examined through simulation and experiments, and the results confirmed that in holographic multiplex recording, the reference-beam angle is not affected by medium shrinkage, and stable recording and reconstruction are achieved.
