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或缺的工具。物理光学公司提议开发一种独特的全分辨率、全彩色3-D显示器，它优于现有设备，并将使神经科学家、临床医生和理论家无需佩戴特殊眼镜即可观看高质量的3-D神经图像。低成本的设计特点是高屏幕亮度和分辨率，而且结构紧凑，没有笨重的光学器件。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工作。此外，它不使用中间组件，如透镜屏、狭缝阵列、护目镜或降低人类视觉系统自然三维感知的眼镜。该方法将背光液晶显示面板与多路开关波导全息图集成在全分辨率显示器中，其自动立体屏幕可作为多个二维显示屏。第一阶段将在一个完整的概念验证演示中达到高潮，其中包括一个交互式场景，在这个场景中，操作员将能够以全动态视差视角观察复杂的物体和场景。建议的商业应用：实时，全彩，低成本的自动立体3d显示系统将找到广泛的商业应用：教育培训和模拟；虚拟现实环境；分子建模;工业检验;CAD在制造业中的应用；医学成像;太空探索;遥控机器人;摄影测量;3-D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.
