چکیده
左右の視差で奥行を知覚する両眼視差方式の 3D映 像ディスプレイシステムは,現在本格的な実用化に 至っている.しかしながら,この方式では水晶体によ るピント調節からもたらされる立体感を刺激しないた め,視距離が近い場合,観察者のふくそうとピントの ずれ,いわゆるふくそう調節矛盾を発生し,眼精疲労 を引き起こす要因となる. 一方,ホログラフィは光の波面そのものを再生する ため,両眼視差だけではなく人間が有する全ての奥行 知覚や運動視差機能を複合的に刺激し,全く違和感の ない完全な 3D映像を再生することができる.古典的 なホログラフィは写真技術であるが,近年のコンピュー タの飛躍的な技術発展に伴い,現在では実在しない 物体の干渉縞を作成することも可能となりつつある. これを計算機合成ホログラム(Computer-Generated Hologram,以下 CGH)と呼ぶ.近年我々は,新しい 計算手法とレーザリソグラフィ技術を用いて超高解像 度 CGHを作成しており,古典的な光学ホログラムに

Computation of Fresnel holograms and diffraction-specific coherent panoramagrams for full-color holographic displays based on anisotropic leaky-mode modulators
We have previously introduced a computational architecture suitable for driving full-color holographic display systems based around anisotropic leaky-mode modulators; this architecture appropriately handles single-sideband modulation and frequency-division multiplexing of spectral bands that correspond to the independent red, green, and blue color channels in the display output. In this paper, ...
متن کاملComputational architecture for full-color holographic displays based on anisotropic leaky-mode modulators
The MIT Mark IV holographic display system employs a novel anisotropic leaky-mode spatial light modulator that allows for the simultaneous and superimposed modulation of red, green, and blue light via wavelength-division multiplexing. This WDM-based scheme for full-color display requires that incoming video signals containing holographic fringe information are comprised of non-overlapping spect...
متن کاملElectrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals using a Michelson interferometer
Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...

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...
