Real-time dynamic holographic image storage device [PDF]

, 1990
A real-time dynamic holographic image storage device uses four-wave mixing in a pair of photorefractive crystals. An oscillation is produced between the crystals which can be maintained indefinitely after the initial object beam is discontinued.

Sub-nanometer free electrons with topological charge

, 2011
The holographic mask technique is used to create freely moving electrons with quantized angular momentum. With electron optical elements they can be focused to vortices with diameters below the nanometer range.

Sequential and non-sequential simulation of volume holographic gratings

Journal of the European Optical Society-Rapid Publications, 2018
Background In the development process of holographic displays like holographic Head-Mounted Displays (hHMD) the simulation of the complete optical system is strongly required.

Holographic optical trapping

, 2005
Holographic optical tweezers use computer-generated holograms to create arbitrary three-dimensional configurations of single-beam optical traps useful for capturing, moving and transforming mesoscopic objects.

The Infrared Imaging Spectrograph (IRIS) for TMT: Volume phase holographic grating performance testing and discussion [PDF]

, 2014
Maximizing the grating efficiency is a key goal for the first light instrument IRIS (Infrared Imaging Spectrograph) currently being designed to sample the diffraction limit of the TMT (Thirty Meter Telescope). Volume Phase Holographic (VPH) gratings have

Method and systems for collecting data from multiple fields of view [PDF]

, 2002
Systems and methods for processing light from multiple fields (48, 54, 55) of view without excessive machinery for scanning optical elements. In an exemplary embodiment of the invention, multiple holographic optical elements (41, 42, 43, 44, 45 ...

Simulation of superresolution holography for optical tweezers [PDF]

, 2008
Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

Photorefractive Crystals As Optical Devices, Elements, And Processors [PDF]

, 1984
The physics of the photorefractive effect and the unique nonlinear optical properties of photorefractive crystals are described. A survey of the optical applications of the photorefractive effect follows. We include the use of photorefractive crystals as

Neutron optical beam splitter from holographically structured nanoparticle-polymer composites

, 2010
We report a breakthrough in the search for versatile diffractive elements for cold neutrons. Nanoparticles are spatially arranged by holographical means in a photopolymer. These grating structures show remarkably efficient diffraction of cold neutrons up
