Abstract
From a single measurement of the signal-to-noise ratio of the image reconstructed from a hologram it is possible to estimate the information capacity of superimposed holograms and to predict the total number of superimposed holograms associated with the maximum information capacity. Information capacity densities of 3.7 x 10(6) bits/mm(3) for Bi(12)TiO(20) crystal samples and 2.3 x 10(8) bits/mm(3) for LiNbO(3) samples have been calculated.Keywords
