DESCRIPTION (provided by applicant): Three-dimensional (3D) imaging and visualization are indispensable in many sectors of the biomedical field. Physical Optics Corporation (POC) proposes to develop a unique high-resolution, full-color liquid crystal flat-panel 3D display that is superior to existing devices, and will enable biomedical researchers, clinicians, and theorists to collaboratively view high-quality, full-color 3D images of biological materials with location-specific correct perspectives and without wearing special glasses or head trackers. The low-cost design features high screen brightness and resolution, and is compact, with no bulky optics. It does not require any special preprocessing or formatting of image data, and can work with standard 3D graphic software and interactive computer systems or with real-time multivideo equipment. Furthermore, it has no intermediate components such as lenticular screens, slit arrays, goggles, or glasses to degrade natural three-dimensional perception of the human vision system. The proposed approach integrates a backlit, optically tiled, very high resolution, liquid crystal flat panel display with spatially multiplexed waveguide holograms in a multiperspective autostereo 3D display whose wide area screen functions as multiple 2D display screens. Phase I will culminate in a full proof-of-concept demonstration of a standard size LCD, on which multiple viewers will be able to look around with a full-motion parallax view of complex objects and scenes. Phase II will produce a compact, high- resolution, large area commercializable prototype system that will be tested in a clinical environment. This real-time, full-color, low-cost multiperspective holographic autostereo liquid crystal 3D display system will find a wide range of commercial applications: educational training and simulation; virtual reality environments; molecular modeling; industrial inspection; CAD for manufacturing; medical imaging; space exploration; telerobotics; photogrammetry; and 3D video and cinema. The proposed holographic automultiscopic liquid crystal 3D display with a natural look-around capability without special eyeware will significantly improve 3D visualization of biomedical images to biomedical researchers, doctors, and surgeons. This capability will aid in screening diagnostics and treatment planning, reducing the duration and cost of surgical procedures.

描述（由申请人提供）：在生物医学领域的许多领域，三维（3D）成像和可视化都是必不可少的。物理光学公司（POC）提议开发独特的高分辨率液晶液晶平板3D显示屏，它优于现有设备，并将使生物医学研究人员，临床医生和理论家能够协作地查看高素质，全彩色的3D图像，具有适当的位置正确的透视和不穿佩戴的鞋类或佩戴特殊佩带或佩戴特色玻璃。低成本的设计具有高屏幕亮度和分辨率，并且紧凑，没有笨重的光学元件。它不需要对图像数据进行任何特殊的预处理或格式化，并且可以使用标准的3D图形软件和交互式计算机系统或实时多维迪科设备。此外，它没有中间组件，例如凸线屏幕，狭缝阵列，护目镜或眼镜可以降低对人类视力系统的天然三维感知。所提出的方法集成了背光，光学瓷砖，非常高的分辨率，液晶平面面板显示屏，并在多重验证的Autostereo 3D显示屏中，带有空间多路复用的波导全息图，其广域屏幕充当多个2D显示屏。第一阶段将在标准尺寸LCD的完整概念验证演示中达到高潮，在该证明中，多个观众将能够在复杂对象和场景的全动作视差视图中四处寻找。第二阶段将产生紧凑的高分辨率，大面积的可商业化原型系统，该系统将在临床环境中进行测试。这个实时的，全彩的低成本多效性全息液晶3D显示系统将找到广泛的商业应用：教育培训和仿真；虚拟现实环境；分子建模；工业检查；制造的CAD；医学成像；太空探索；远程植物学；摄影测量；以及3D视频和电影。所提出的具有自然外观能力的全息液晶液晶3D显示器，没有特殊的眼神，将显着改善生物医学研究人员，医生和外科医生的生物医学图像的3D可视化。这种能力将有助于筛查诊断和治疗计划，减少手术程序的持续时间和成本。
