True Three Dimensional Display For Medical Telepresence

描述(由申请人提供)：该SBIR二期项目的目标是开发和构建一种独特的、创新的真三维(3D)显示器的工程演示版本，用于3D医疗数据和医疗网真应用。目前存在许多伪3D显示器--通常是立体/双视，或者一次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，在使用中通常不是很令人满意。真正的3D显示(移动您的头-看到不同的东西)将极大地改进远程(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)的共享。。。)或者在仪器上，或者在联网的站点之间。拟议中的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不存在问题。这项拟议的研究的目标是生产一种紧凑、经济高效的真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度切片通道。在它的多通道版本中，这款设备不仅将为每只眼睛呈现不同的无护目镜高分辨率视图(立体视觉--真3D的一个要求)，而且还将具有视差或环视-当观看者移动头部或移动到不同位置时，她将看到不同的东西-就像现实世界一样。 电光组件、照明源和计算速度的技术水平已经发展到现在可以创建真正的3D显示器的地步。第三维度技术第一阶段的一个项目从理论和实验上证明了全息立体摄影(使用胶片同时显示一个物体的多个静态真3D图像)的概念可以转化为电子时代。数字组件和全息光学元件将许多角度切片通道组合成真正的3D视图。该第二阶段SBIR项目将在第一阶段项目的理论和实验结果的基础上，开发和构建至少20个通道的角度切片True 3D显示器的硬件和软件。

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.
