Paper Abstract

The storage capacity of the random phase-coded volume hologram multiplexing which uses a ground glass as the random phase diffuser is reported. We found that the role of the ground glass imply the storage capacity of the random phase-coded multiplexing. From the experimental results, the tolerance of the position mismatch of the decoding ground glass is with a typical value of decades of micrometers, as reading an image. On the other hand, from the computer simulation, the signal-to-noise ratio of the readout images can be obtained by the pixel size of the ground glass. After mainly considering the tolerance of the position mismatch of the ground glass and the signal-to-noise ratio of the reconstructed image, the storage capacity of the random phase-coded multiplexing can be estimated.
