Highly photorefractive hybrid liquid crystal device for a video-rate holographic display.
In this paper, we demonstrate a dynamic holographic display in a quantum dot (ZnS/InP) doped liquid crystal device, where one of the interior cell surfaces is covered by a ZnSe layer. Such a hybrid device shows substantially improved photorefractive sensitivity of 2.2 cm3/J, which is almost 300 times larger than that in ZnS/InP doped liquid crystal device without the ZnSe layer. The ...
متن کاملOptoelectronic Device using a Liquid Crystal Holographic Memory
Recently, the technologies related to liquid crystal spatial light modulators have progressed dramatically [1]–[4]. Such modulators are classifiable as two types: transmissive and reflective. Both types are used widely for various applications, e.g. liquid crystal television panels, personal computer displays, and projector systems. In particular, the resolution of the latest liquid crystal spa...
متن کاملNear-infrared sensitive photorefractive device using polymer dispersed liquid crystal and BSO:Ru hybrid structure.
A near-infrared sensitive hybrid device, based on a Ru-doped BSO photorefractive substrate and polymer dispersed liquid crystal (PDLC) layer, is reported. It is found that the photoexcited charge carriers generated in the BSO:Ru substrate create an optically induced space charge field, sufficient to penetrate into the PDLC layer and to re-orient the LC molecules inside the droplets. Beam-coupli...
متن کاملCircular holographic video display system.
A circular holographic video display system reconstructs holographic video. Phase-only spatial light modulators are tiled in a circular configuration in order to increase the field of view. A beam-splitter is used to align the active area of the SLMs side by side without any gap. With the help of this configuration observers can see 3D ghost-like image floating in space and can move and rotate ...
متن کاملAccurate control of a liquid-crystal display to produce a homogenized Fourier transform for holographic memories.
We show an accurate procedure to obtain a Fourier transform (FT) with no dc term using a commercial twisted-nematic liquid-crystal display. We focus on the application to holographic storage of binary data pages, where a drastic decrease of the dc term in the FT is highly desirable. Two different codification schemes are considered: binary pi radians phase modulation and hybrid ternary modulati...
