11-7 Wavefront Compensation in Holographic Memory with High Resolution Bit Data

Abstract

Hologram distortion can be compensated by controlling wavefront of the reference beam while reproducing. However, some wavefronts degrade high resolution bit data. We obtained wavefornt to compensate for hologram distortion without degradation of bit data by limiting moving distance of a deformable mirror. As a result, a bit error rate of the reproduce data could be decreased.
