Comparison of transmission and the 90-degree holographic recording geometry

Y Yang, A Adibi, D Psaltis - Applied optics, 2003 - opg.optica.org
We compare the system performances of two holographic recording geometries using iron-
doped lithium niobate: the 90-degree and transmission geometry. We find that transmission …

Thermal fixing of 10,000 holograms in LiNbO3:Fe

X An, D Psaltis, GW Burr - Applied Optics, 1999 - opg.optica.org
We discuss thermal fixing as a solution to the volatility problem in holographic storage
systems that use photorefractive materials such as LiNbO_3: Fe. We present a systematic …

Dynamic holographic memory showing readout, refreshing, and updating capabilities

S Boj, G Pauliat, G Roosen - Optics letters, 1992 - opg.optica.org
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 …

Multilayer volume holographic optical memory
