A modified signal channel of holographic memory is proposed and studied theoretically and experimentally. Compared with a conventional optical scheme, the channel enables to decrease the spread in signal of reconstructed images of information elements, which is caused by their interference in the case of a restricted Fourier hologram aperture, increase the signal-background ratio, and reduce the sensitivity to misalignment of the image and the photodetector array.
