Persistent holograms are recorded locally with red light in a LiNbO_3 crystal doped with Mg
and Fe. Selective erasure is realized by use of a focused UV sensitizing light. We …

We demonstrate a scheme for volume holographic storage based on the features of shift
selectivity of a speckle reference-wave hologram. The proposed recording method permits …

We analyze the mechanisms leading to a highly diffractive fixed hologram in photorefractive
Fe-doped lithium niobate crystals by simultaneous self-stabilized holographic recording and …

Volume holographic recording and storage in Fe‐doped LiNbO3 using single 30–75‐nsec
duration optical pulses at 694.3 and 531 nm from Q‐switched ruby and frequency‐doubled …

We propose a new refreshing procedure for reading out a dynamic holographic memory
without loss of information. The retrieved images are fed back to the memory after being …

Digital holograms have been written in stoichiometric Pr: LiNbO_3 in a two-color recording
scheme, demonstrating what is to our knowledge the first all-optical nondestructive readout …

Holographic gratings are written in photorefractive Sr_0. 61Ba_0. 39Nb_2O_6 crystals by
two interfering light beams. Angular-dependent readout of the holograms shows that …

Holography in the Gabor regime is restricted to weak diffraction assumptions. Otherwise,
diffraction prevents an accurate recovery of the object's complex wavefront. We have …

We experimentally demonstrate and characterize a memory module that features selective
page erasure and readout persistence using the localized recording method in doubly …

We report on faithful reconstruction in polarization holography independent of the exposure
time and the reading wave that is suitable for high-speed recording and reconstructing …
