[19p-Z28-13] Detection of phase encoded signals in polychromatic reconstruction

Keywords:holographic data storage, polychromatic reconstruction, single-shot phase detection

The polychromatic reconstruction method makes it possible to reconstruct a volume hologram at an arbitrary wavelength, and shows excellent performance such as high-density recording and wide reconstruction tolerance in the memory system. In this study, we propose to apply this polychromatic reconstruction method to a phase-encoded holographic memory system. We report on a method for improving the small data transfer rate, which is a problem of this method.
