Three-dimensional (3-D) imaging and visualization are indispensable tools in many sectors of the biomedical field. Physical Optics Corporation proposes to develop a unique full resolution, full-color 3-D display that is superior to existing devices, and will enable neuroscientists, clinicians, and theorists to view high quality 3-D neuroimages without wearing special glasses. The low-cost design features high screen brightness and resolution, and is compact, with no bulky optics. It does not require any preprocessing or formatting, and can work with standard interactive computer systems and video equipment. Furthermore, it uses no intermediate components such as the lenticular screens, slit arrays, goggles, or glasses that degrade the natural three-dimensional perception of the human vision system. The proposed approach integrates a backlit liquid crystal display flat-panel with multiplexed switching waveguide holograms in a full resolution display whose autostereoscopic screen functions as multiple 2-D display screens. Phase I will culminate in a full proof-of-concept demonstration, including an interactive scenario in which the operator will be able too look around with a full-motion parallax view of complex objects and scenes. PROPOSED COMMERCIAL APPLICATION: A real-time, full-color, low-cost autostereoscopic 3-D display system will find an enormous range of commercial applications: education training and simulation; virtual reality environments; molecular modeling; industrial inspection; CAD applications in manufacturing; medical imaging; space exploration; telerobotics; photogrammetry; and 3-D video and cinema.

三维（3-D）成像和可视化是生物医学领域许多领域中必不可少的工具。 物理光学公司建议开发独特的完整分辨率，全彩3-D显示屏，比现有设备优于现有设备，并将使神经科学家，临床医生和理论家能够查看高质量的3-D神经图像而不戴特殊眼镜。 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。 它不需要任何预处理或格式化，并且可以使用标准的交互式计算机系统和视频设备。 此外，它不使用中间组件，例如凸出的屏幕，狭缝阵列，护目镜或眼镜，可以降低对人类视力系统的自然三维感知。 所提出的方法在完整的分辨率显示器中集成了背光液晶显示平板，其自动镜屏幕充当多个2-D显示屏屏幕。 第一阶段将在完整的概念验证演示中达到高潮，包括一个交互式场景，在该场景中，操作员也可以通过对复杂对象和场景的全动态视差视图来环顾四周。拟议的商业应用程序：实时，全彩，低成本的自动镜3-D展示系统将找到大量的商业应用程序：教育培训和模拟；虚拟现实环境；分子建模；工业检查；制造中的CAD应用；医学成像；太空探索；远程植物学；摄影测量；以及3-D视频和电影院。
