Horizontal-parallax-only holographic stereograms of nearly SDTV resolution (336 pixels by 440 lines by 96 views) of textured and normal-mapped models (500 polygons) are rendered at interactive rates (10 frames/second) on a single dual-head commodity graphics processor for use on MIT’s third-generation electro-holographic display. The holographic fringe pattern is computed by a diffraction speci...

Holographic speckle is a major impediment for the emerging applications of multiphoton holographic projection in biomedical imaging, photo-stimulation and micromachining. Time averaging of multiple shifted versions of a single hologram ("shift-averaging") is a computationally-efficient method that was recently shown to deterministically eliminate holographic speckle in single-photon application...

Owing to the limited spatio-temporal resolution of display devices, dynamic holographic three-dimensional displays suffer from a critical trade-off between the display size and the visual angle. Here we show a projection-type holographic three-dimensional display, in which a digitally designed holographic optical element and a digital holographic projection technique are combined to increase bo...

2 p m Ioannis Papadimitriou (CERN) on "Holographic renormalization for generic Hamiltonian systems and application to Improved Holographic QCD" Where : 2nd floor seminar room Calendar: University of Crete HEP Seminars Description: ABSTRACT: Holographic renormalization has emerged as a systematic method for addressing certain pathologies, such as large distance divergences of the on-shell action...

Recent optical and computer graphic methods have produced the "alcove" holographic stereogram that is capable of reconstructing in laser light an undistorted 3-D projected image from a series of 2-D views on a concave surface. This technique requires only one holographic step to obtain an undistorted real image stereogram, formerly accomplished by two separate holographic procedures. The hologr...

Holographic neural networks are a new and promising type of artificial neural networks. This article gives an overview of the holographic neural technology and its possibilities. The theoretical principles of holographic networks are first reviewed. Then, some other papers are presented, where holographic networks have been applied or experimentally evaluated. A case study dealing with currency...

Minsik Park et al. 1 http://dx.doi.org/10.4218/etrij.14.2113.0086 A holographic display system with a 22-inch LCD panel is developed to provide a wide viewing angle and large holographic 3D image. It is realized by steering a narrow viewing window resulting from a very large pixel pitch compared to the wave length of the laser light. Point light sources and a lens array make it possible to arbi...

The holographic bound states that the entropy in a region cannot exceed one quarter of the area (in Planck units) of the bounding surface. A version of the holographic principle that can be applied to cosmological spacetimes has recently been given by Fischler and Susskind. This version can be shown to fail in closed spacetimes and they concluded that the holographic bound may rule out such uni...

Polymerisation induced shrinkage is one of the main reasons why photopolymer materials are not more widely used for holographic applications. The aim of this study is to evaluate the shrinkage in an acrylamide photopolymer layer during holographic recording using holographic interferometry. Shrinkage in photopolymer layers can be measured by real time capture of holographic interferograms durin...

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 the focal length of the combination of the two lenses. The zoom ratio of the holographic projection system can reach 3.7:1 with continuous zoo...
