Organization of data for monochromatic multiplex volume holography

Journal of the Optical Society of America A: Optics and Image Science, and Vision, 1996
We derive the relationships for coded wave fronts in volume holography for reference and signal waves coded with two-dimensional wave fronts. We develop estimates for cross talk that is due to grating degeneracy, nonorthogonality, and momentum-mismatch reconstruction.

Transformational volume holography

Journal of the Optical Society of America A, 2014
We analyze the bulk elastic transformation of volume holograms as a general approach for three-dimensional pupil engineering. The physical relationship between transformation and the resulting point spread function is discussed by deriving the corresponding analytical expressions. For affine transformations, an analytical solution is directly possible.

Associativity in volume holography

Optics Communications, 1977
Abstract We show theoretically and experimentally that associative connections between image structures are performed with advantage in thick media.

Volume holography-based abrupt autofocusing beam

Applied Optics, 2023
Volume holographic elements are excellent at shaping high-quality spatial and spectral modes. Many microscopy and laser–tissue interaction applications require precise delivery of optical energy at specific sites without affecting the peripheral regions.

Coded-wavelength multiplex volume holography

Optics Letters, 1995
We introduce the technique of coded-wavelength multiplex holography. We encode each wavelength with a discrete angular spectrum of plane waves, so that the total number of multiplexed holographic pages equals the number of wavelengths multiplied by the number of discrete wave vectors at each wavelength.

Generalized Bragg selectivity in volume holography

Applied Optics, 2002
The 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.

Volume holography for 1550nm digital databases

Diffractive Optics and Micro-Optics, 2000
It’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 ...
