Paper Abstract

The method to do an shift multiplexing by using spherical reference light was examined. The density growth can be expected by overwriting the hologram using spherical reference light. The hologram recording is carried out by shifting the block where the multiplexed hologram was recorded. In addition, a further large capacity can be expected by using the transmission type together with the reflection type hologram recording. In this paper, the result of verifying fundamental proof of these methods was reported by the record reproduction experiment.
