| Abstract(in English) | Hologram distortion caused by shrinkage of photopolymer materials can be compensated optically by controlling wavefront of the reference beam while reconstructing. However, in angle-multiplexed holograms, crosstalk from neighboring data page occurs when wavefront of the reference beam is quite different from plane wave. Then, based on the angular gap between neighboring data pages, we investigated moving distance of the deformable mirror which produces any types of wavefront of the reference beam entering hologram. As a result, by restricting moving distance of the deformable mirror so as to become that angle at any position of the minor is less than half of the angular gap between neighboring data pages, reconstructed image without crosstalk could be obtained. |
