Evaluation Experiments On Holographic Storage Of Binary Data In Electro-Optic Crystals

From extensive measurements of diffracted power distributions from binary-data-page holograms, the probabilities of bit error are calculated to be as low as 5 x 10-8 for volume Fourier transform holograms in iron-doped lithium niobate. Results are determined as a function of reference beam angular position for different diffraction efficiencies, for the angularly multiplexed superposition of holograms with dif-ferent angular separations, and for different displacements of the Fourier transform plane from the electro-optic crystal.
