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.

描述（由申请人提供）：该II阶段SBIR项目的目标是开发和建立一个独特而创新的真正三维（3D）显示器的工程演示版本，可与3D医疗数据以及在医疗触发应用中一起使用。目前有许多伪-3D显示器 - 通常立体/两视图，或一次投影到一个体积显示器上，或需要玻璃/护目镜。这些显示都遭受了各种问题的困扰，通常使用并不令人满意。真正的3D显示器（移动您的头 - 看到不同的东西）将极大地改善遥远的（远程）机器人手术，医学教学，诊断，并共享三维类型的医学数据（CT扫描，MRI扫描，PET扫描，声学扫描，声学扫描，或者在仪器之间或在网络站点之间）。提出的3D显示屏使用宽带照明（“白光”，而不是激光器），因此对设备的眼部安全没有任何疑问。拟议的研究的目的是生产紧凑，成本效益，真实的3D显示投影仪。 I阶段SBIR可行性项目已成功证明了此类3D显示屏的两个全彩角式通道。该设备将在其多通道版本中不仅显示出无goggles的高分辨率高分辨率不同的视图（立体声 - 对True 3D的要求），而且还将具有视差或远程视图 - 当观众移动她的头或移动到另一个位置时，她会看到不同的位置，就像现实世界一样。 电光组件，照明源和计算速度的最新技术已经发展到现在可以创建真正的3D显示屏的位置。第三维技术I期项目在理论上还是在实验上都表明，全息刻度的概念（使用胶片同时显示静态true 3D对象的许多视图）可以翻译成电子时代。数字组件和全息光学元素将许多角切片通道结合到真实的3D视图中。该阶段II SBIR项目将基于I阶段项目的理论和实验结果，以开发和构建至少20个Angular Slice True 3D显示的硬件和软件。
