True Three Dimensional Display For Medical Telepresence

描述（由申请人提供）：该阶段II SBIR项目的目标是开发和构建一个独特的、创新的真正三维（3D）显示器的工程演示版本，用于3D医疗数据和医疗远程呈现应用。目前存在许多伪3D显示器-通常是立体/双视图，或者一次将一个平面投影到体积显示器上，或者需要眼镜/护目镜。这些显示器都存在各种问题，并且在使用中通常不是很令人满意。一个真正的3D显示器（移动你的头-看到不同的东西）将极大地改善远程（远程呈现）机器人手术，医疗教学，诊断和三维医疗数据（CT扫描，MRI扫描，PET扫描，声学扫描，. . .)或者在仪器处或者在联网的站点之间。所提出的3D显示器使用宽带照明（“白色光”，而不是激光），因此不存在关于设备的眼睛安全性的问题。拟议的研究的目标是生产一个紧凑的，具有成本效益的，真正的3D显示投影仪。第一阶段SBIR可行性项目已经成功地展示了这种3D显示器的两个全色角切片通道。该设备将在其多通道版本中不仅为每只眼睛呈现无护目镜的高分辨率不同视图（立体视觉-真正的3D的一个要求），而且还将具有视差或环视-当观看者移动她的头部或移动到不同的位置时，她将看到不同的东西-就像真实的世界一样。 电光元件、照明源和计算速度的最新技术水平已经发展到现在可以创建真正的3D显示器。Third Dimension Technologies第一阶段的项目在理论上和实验上都表明，全息立体摄影（使用胶片同时显示物体的多个视图以实现静态真实3D）的概念可以转化为电子时代。数字组件和全息光学元件联合收割机将许多角度切片通道组合成真正的3D视图。第二阶段SBIR项目将建立在第一阶段项目的理论和实验结果的基础上，为Angular Slice True 3D显示器的至少20个通道开发和构建硬件和软件。

DESCRIPTION (provided by applicant): The goal of this Phase II SBIR project is to develop and build an Engineering Demonstration version of a unique and innovative truly three-dimensional (3D) display for use with 3D Medical data and in Medical Telepresence applications. There are presently many pseudo-3D displays - generally stereoscopic/two-view, or projection of one plane at a time on to a volume display, or requiring glasses/goggles. These displays all suffer from various problems, and are generally not very satisfactory in use. A truly 3-D display (move your head - see something different) would tremendously improve remote (telepresence) robotic surgery, medical teaching, diagnosis, and sharing of three-dimensional kinds of medical data (CT scans, MRI scans, PET scans, acoustic scans, . . .) either at the instrument or between networked sites. The proposed 3D display uses broadband illumination ("white light", not laser) so that there are no questions about eye-safety of the device. The proposed research has the goal of producing a compact, cost-effective, true 3D display projector. The Phase I SBIR feasibility project has successfully demonstrated two full-color angular-slice channels of such a 3D display. This device will in its many-channel version not only present a no-goggles high-resolution different view to each eye (stereopsis - one requirement for true 3D), but will also have parallax or look-around - when a viewer moves her head or moves to a different position she will see something different - just like the real world. The state of the art in electro-optic components, illumination sources, and computational speed has advanced to the point that it is now feasible to create a truly 3D display. A Third Dimension Technologies Phase I project has shown both theoretically and experimentally that the concepts of holographic stereography (which uses film to simultaneously display many views of an object for static true 3D) can be translated into the electronic age. Digital components and a holographic optical element combine many Angular Slice channels into a true 3D view. This Phase II SBIR project will build on the theoretical and experimental results from the Phase I project to develop and construct the hardware and software for at least 20 channels of an Angular Slice True 3D Display.
