Selective Erasure of Multiplexed Holograms in Fe:LiNbO₃ by Complementary Holography

To study the selective erasure and rewriting of the multiplexed holographic storage in photorefractive crystals. According to the mechanism on forming of phase hologram in photorefractive crystal, by incoherently addition of the complementary hologram and the original hologram, the selective erasure and rewriting were accomplished. The complementary holography is an effective and convenient technique for selective erasure and rewriting of multiplexed holographic storage in photorefractive crystals.
