FREE VIEWING 3-D DISPLAYS FOR NEUROIMAGING APPLICATION

三维成像和可视化是生物医学领域许多领域不可缺少的工具。物理光学公司计划开发一种独特的全分辨率、全彩色3D显示器，这种显示器优于现有设备，将使神经科学家、临床医生和理论家能够在不戴特殊眼镜的情况下观看高质量的3D神经图像。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，可以与标准的交互式计算机系统和视频设备一起使用。此外，它不使用中间部件，如透镜屏幕、狭缝阵列、护目镜或眼镜，这些部件降低了人类视觉系统的自然三维感知。该方法将背光液晶显示平板和多路开关波导全息图集成在一个全分辨率显示中，其自动立体屏起到多个2-D显示屏的作用。第一阶段将在完整的概念验证演示中达到高潮，其中包括一个交互场景，在该场景中，操作员也将能够通过复杂对象和场景的全运动视差查看周围。拟议的商业应用：一种实时、全彩色、低成本的自动立体三维显示系统将获得巨大的商业应用范围：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；空间探索；远程机器人；摄影测量；以及三维视频和电影。

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.
