MODEL FOR THE EFFECTS OF MATERIAL SHRINKAGE ON VOLUME HOLOGRAMS

A model for analyzing the effects of material shrinkage on volume holo grams is presented. This model is based on the fringe-plane rotation m odel used for describing the effects of plane-wave grating holograms t hat undergo shrinkage. A computer was used to exercise the model for a simple input object typical of those used in digital holographic memo ry applications and stored as a Fourier-transform hologram. The theore tical formulation of the model is presented as well as the results of the numerical analysis.
