Compensation for pixel-mismatch errors in shift-multiplexed holographic data storage

Author(s): Sungphil Kim, Seok Ho Song, Jideog Kim, and Hong-Seok Lee


“To read out correct data from shift-multiplexed holographic data storage, we propose a novel method of pixel matching by use of a tiny plane-parallel refraction plate placed in the path of converging readout beams. Tilting the refraction plate produces a shift in the lateral position of the readout beam incident upon the holographic storage disk, leading to compensation for pixel-mismatch errors by an improvement in bit-error rate of 3 orders of magnitude.”
