Abstract : This report describes the results of the currently obtainable signal/noise (S/N) ratio of images readout from thick phase holograms stored in iron-doped LiNbO3. Using multiple object beam illumination an S/N ratio of approximately 27 dB was measured for a white field. No significant decrease in the measured S/N ratio was observed with the increasing number of holograms stored. (Author)
