Hologram distortions occurs due to shrinkage when photopolymer material is used. We found that the wavefront of the reference beam to compensate for hologram distortion at a data page is similar to that at neighboring data pages in angle multiplexed holograms. Then, we recorded 80 data pages with angle-multiplexing and obtained optimized wavefront to compensate for hologram distortion at first, fortieth and eightieth data pages by using adaptive optics and estimate wavefronts at the other data pages by using interpolation of these optimized wavefronts. When data are reproduced by using these wavefronts, bit error rates of reproduced data decrease at all data pages. |
