Abstract Characteristics of holography using binary photosensitive materials were investigated by analytical calculations and computer simulations in relation to the hologram recording conditions. It was concluded that by choosing proper intensities of object beam and reference beam for the threshold of the photoresponse, some degree of fidelity can be attained in the reconstructed images. It was also concluded that in the holographic memory where a page composer of a bit array is used, the number of the bits of the array should be limited to a small number (say 10 to 20 for one dimension) to get a clear distinguishability between "1" and "0". The above results are applicable to the holographic recording on magnetooptic thin films which are more or less binary in their photoresponse.
