Abstract
Experiments have been performed in which 1000 holograms have been superimposed one upon the other in the same area of photographic emulsion. Each hologram was formed with a uniquely coded reference beam allowing reconstruction of only one of the superimposed holograms while the unaddressed holograms contribute incoherent noise. Signal-to-noise ratios are calculated and measured as a function of the number of superimposed exposures. For the 1000-exposure hologram, the observed signal-to-noise ratio for any one of the individual holograms was 10 dB.
