Depth formulation assessment of 1D light field display using self-interference incoherent digital holography

Journal of Information Display
Light field display based on a lenticular lens is currently the most commercially available three-dimensional (3D) display system that can only provide one-dimensional (1D) parallax.

Analysis of the phase images obtained during the collection of a holographic registration system based on the geometric phase effect and a polarization camera

Научно-технический вестник информационных технологий, механики и оптики
The results of measuring the surface depth of the test object using digital holography are presented. The resulting image was compared to a model based on the calibration slide documentation.

Imaging quality evaluation of photopolymer holographic lenses

, 2007
A method to obtain holographic lenses in phtopolymer is presented. The imaging quality of these lenses is evaluated by means of the modulation transfer function (MTF). Lenses of different focal lengths have been recorded.

Volume Holographic Hyperspectral Imaging [PDF]

, 2004
A volume hologram has two degenerate Bragg-phase-matching dimensions and provides the capability of volume holographic imaging. We demonstrate two volume holographic imaging architectures and investigate their imaging resolution, aberration, and ...

THEORY OF OPTICAL TRANSFORMATION BY A SINGLE HOLOGRAPHIC LENS

Acta Physica Sinica, 1981
It is shown for the case of a discrete sample that an arbitrary transformation can be realized by an optical system composed of a single holographic lens. The design of the amplitude and phase distribution of the single holographic lens for the purpose of realizing a given transformation is given. The amplitude and phase distribution of the holographic

A holographic projection system with an electrically tuning and continuously adjustable optical zoom

, 2012
A holographic projection system with optical zoom is demonstrated. By using a combination of a LC lens and an encoded Fresnel lens on the LCoS panel, we can control zoom in a holographic projector. The magnification can be electrically adjusted by tuning

Solar tracking with no movable parts using multiplexed holographic lenses for photovoltaic application

, 2013
Acceptance angle of thick phase transmission holographic lenses is generally small and is comparable to conventional concentrating system. This paper presents theoretical optimization of recording parameters to increase acceptance angle of a single ...
