Autostereoscopic 3D flat panel display using an LCD-pixel-associated parallax barrier

This letter reports an autostereoscopic three-dimensional （3D） fiat panel display system employing a newly designed LCD-pixel-associated parallax barrier （LPB）. The battler＇s parameters can be conveniently determined by the LCD pixels and can help to greatly simplify the conventional design. The optical system of the proposed 3D display is built and simulated to verify the design. For further experimental demonstration, a 508-mm autostereoscopic 3D displayprototype is developed and it presents good stereoscopic images. Experimental results agree well wlth the simulation, which reveals a strong potential for 3D display applications.

全息影像的视觉真实性观念及其对当代视觉文化的表征

全息影像的独特价值在于其所营造的逼真的视觉体验,其所带来的根本性问题是重新诠释的视觉真实性观念,确切地说,正是这种新的视觉真实性观念促成了全息影像技术的诞生和发展。全息影像的视觉真实性观念包含模拟现实的视像真实、观看者现实性在场和超越现实的视觉真实三个层面。全息影像的视觉真实性观念表达了当代视觉文化对视觉真实性的特定理解,表征了当代视觉文化追求仿真(模仿全息光学原理下的可见世界)视像、虚拟生存观看、视觉奇幻体验的视觉理念。
