Cross talk in holographic memories with lensless phase-conjugate holograms.

Author information

System and Control Sector, Samsung Advanced Institute of Technology, Suwon, Korea.


Recently holographic memory with lensless phase-conjugate holograms has attracted much attention because it opens up the possibility of compact holographic memories. We investigate cross-talk noise in compact holographic memories with angular multiplexing. It turns out that the optimum angular separation is the same as that for the Fourier plane hologram in the leading order and that the noise-to-signal ratio is independent of the positions in the output plane, similar to the case of the image plane hologram.
