True Three Dimensional Display For Medical Telepresence

描述（由申请人提供）：这个第二阶段SBIR项目的目标是开发和构建一个独特和创新的真正三维（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。目前有许多伪3d显示-通常是立体/双视图，或一次将一个平面投影到体积显示上，或需要眼镜/护目镜。这些显示器都有各种各样的问题，在使用中通常不是很令人满意。一个真正的3-D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、医学教学、诊断，以及在仪器或网络站点之间共享三维医学数据（CT扫描、核磁共振扫描、PET扫描、声学扫描等）。提议的3D显示器使用宽带照明（“白光”，而不是激光），因此设备的眼睛安全没有问题。提出的研究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。一期SBIR可行性项目已经成功演示了这种3D显示器的两个全彩角切片通道。该设备的多通道版本不仅可以为每只眼睛提供不带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），而且还可以视差或环顾四周-当观众移动她的头或移动到不同的位置时，她会看到不同的东西-就像现实世界一样。

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.
