Storage of 64 images (128 x 128 pixels) by the deterministic phase-encoding technique in a holographic memory is reported. A ferroelectric phase modulator permits a fast random image reconstruction (150 As/image). Sources of cross talk arising from the imperfections of the optical components are studied and evaluated.
