Abstract—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.
Key words: holographic memory, optical system, reconstructed image.
