Hologram multiplexing using two-step recording

Demetri Psaltis

We present a comparison of different two-step holographic recording schemes based on their multiplexing performance using a unified framework. The difference between the different schemes is mainly due to the energy levels and sources of the traps. The inf ...

High-density recording in photopolymer-based holographic three-dimensional disks

Demetri Psaltis

The performance specifications of a holographic three-dimensional disk system are experimentally characterized. A surface density of 10 bits/mu m(2) is experimentally demonstrated with a 100-mu m-thick photopolymer as the recording medium. (C) 1996 Optical ...

Holographic Storage Using Shift Multiplexing

Demetri Psaltis

We demonstrate theoretically and experimentally a new multiplexing method for volume holographic storage using a single reference beam that is composed of multiple plane waves or is a spherical wave. We multiplex the holograms by shifting the recording mat ...

Holographic 3-D Disks

Demetri Psaltis

The performance characteristics of an experimental holographic 3-D disk system are described. A surface density of 10 bits/mu(2) is experimentally demonstrated using a 100 mu m thick photopolymer as the recording medium. ...

Information capacity of 3-D holographic data storage

Demetri Psaltis

Capacities for angular and wavelength multiplexed holographic data storage systems are considered. Limitations due to the spatial resolution of the recording and reconstructing fields and to the holographic recording process are derived. © 1993 Chapman & H ...

Microendoscopic holography with flexible fiber bundle: experimental approach

Christian Depeursinge

An `in situ' holographic technique, based on the use of a flexible miniaturized endoscope (diameter less than 1 mm) has been developed for medical applications. The holographic process provides quantitative information on the 3-D geometry of the observed s ...
