Generalized Bragg selectivity in volume holography
Applied Optics, 2002The diffraction efficiency of holographically recorded volume gratings was extensively studied, and it can be accurately predicted as long as the recording wave fronts are simple. The derivation of the diffraction efficiency when complicated wavefronts or images are involved is much more tedious and less explored.

Physics Reports, 1981
Abstract The major objective of this review is to describe the various theoretical techniques which have been used to model the reconstruction process in a volume hologram. Extensive reference is made to theories of scattering of waves by three-dimensional diffraction gratings in related areas of study.

Volume holography for 1550nm digital databases
Diffractive Optics and Micro-Optics, 2000It’s well known that volume holography makes it possible to record real information databases by overlapping multiple holograms within the same volume and accessing them independently. Furthermore in the last years the increasing achievement of optical communication systems operating in the third window of optical communication systems (1550nm) is ...

Nonlinear Volume Holography for Wave-Front Engineering
Physical Review Letters, 2014The concept of volume holography is applied to the design of an optical superlattice for the nonlinear harmonic generation. The generated harmonic wave can be considered as a holographic image caused by the incident fundamental wave. Compared with the conventional quasi-phase-matching method, this new method has significant advantages when applied to ...

Volume holography in flowing liquids
Annual Meeting Optical Society of America, 1987The volume holography process in a sensitized fluid is studied. The object of the research is to use forced Rayleigh scattering methods in the measurement of velocity gradients in fluids. The process is divided into three major steps: writing of the hologram; evolution of the hologram under the effect of fluid motion; and reading of the hologram by ...

Volume holography of transient optical fields
Soviet Journal of Quantum Electronics, 1973It is shown that interaction between an optical signal and a special nonmonochromatic reference wave with a bulk light-sensitive material can be used to record information on the spatial and temporal characteristics of the signal. Illumination of a hologram obtained in this way with a special reconstructing wave produces a three-dimensional time ...

The Beam Ratio in Volume Holography
Journal of Modern Optics, 1988Abstract Holograms for potential use as optical interconnects in micro-electronic circuits can be recorded optically by either sequential or simultaneous exposures. It is desirable that these holograms have the highest possible diffraction efficiency.
