描述(申请人提供)：三维(3D)成像和可视化在生物医学领域的许多领域都是不可或缺的。物理光学公司(POC)提议开发一种独特的高分辨率、全彩色液晶平板3D显示器，该显示器优于现有设备，将使生物医学研究人员、临床医生和理论家能够以特定位置的正确视角协作查看高质量的全彩色生物材料3D图像，而不需要佩戴特殊的眼镜或头部追踪器。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，并且可以与标准3D图形软件和交互式计算机系统或实时多视频设备一起使用。此外，它没有中间部件，如透镜屏幕、狭缝阵列、护目镜或眼镜，以降低人类视觉系统的自然三维感知。该方法将背光、光学拼接、非常高分辨率的液晶平板显示器与空间多路复用的波导全息图集成在一个多视角自动立体3D显示器中，其广域屏幕具有多个2D显示屏的功能。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，多名观众将能够在其上观看复杂对象和场景的全动态视差视图。第二阶段将生产一个紧凑、高分辨率、大面积可商业化的原型系统，并将在临床环境中进行测试。这种实时、全彩色、低成本的多视角全息自动立体液晶3D显示系统将获得广泛的商业应用：教育培训和模拟；虚拟现实环境；分子建模；工业检查；用于制造的CAD；医学成像；空间探索；远程机器人；摄影测量；以及3D视频和电影。提出的全息自动液晶3D显示器具有自然环视能力，无需特殊的眼镜，将显著改善生物医学图像的3D可视化，为生物医学研究人员、医生和外科医生提供便利。这种能力将有助于筛查诊断和治疗计划，减少手术过程的持续时间和成本。

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.
