Abstract

This paper reports new possibilities for increasing the information capacity of 3-D holograms. It is based on the application of the speckle wave as a reference under the volume hologram recording. Such hologram has the translational selectivity (the sensitivity of the diffracted wave amplitude to the mutual translational shift of the hologram and the reconstructing beam) and the angular selectivity which doesn't depend on the changing of the rotational axis. All these possibilities arise due to the space mismatch between the recorded structure and the reconstructing speckle wave. The theoretical analysis and experimental study of this problem under the volume holograms recording at the LiNbO3:Fe crystals were carried out.
