DESCRIPTION (provided by applicant): The goal of this Phase I SBIR project is to demonstrate the feasibility of a high-resolution truly three-dimensional (3D) color display for use in Medical data display applications. Such a display would tremendously improve remote (telepresence) medical teaching, diagnosis, and viewing of three-dimensional kinds of medical data (CT scans, MRI scans, PET scans, acoustic scans,...). The display would use broadband ("white light", not laser) illumination so that there are no questions about eye-safety of the device. While there are presently pseudo-3D displays (generally stereoscopic, or projection of one plane at a time on to a volume display, or requiring goggles) and at least one display that projects laser light onto a globe, none of these recreates the true three-dimensional light wave at the eye. These displays therefore all suffer from various problems, and are generally clumsy and not very satisfactory in use. The proposed research has the goal of producing a compact, cost-effective, 3D display projector. The state of the art in electro-optic components, illumination sources, and computational speed has advanced to the point that with high probability (but also with high risk) it is feasible to create a truly three dimensional (holographic) display that can be used to project three-dimensional medical images for medical teaching, assisting less-skilled personnel in medical diagnosis, and sharing of three-dimensional medical data over the internet between medical experts in the same or different fields. This Phase I SBIR project will investigate both the hardware and computational feasibility of creating this holographic display with available (though state of the art) electro-optic components and computational resources. The expected outcome is demonstration of feasibility of the 3D display, along with a conceptual display design for use in actual design and construction of a prototype 3D display in Phase II of the project. Though highly risky, success in this endeavor will be a terrific win for medical telepresence and 3D data display applications.

描述（由申请人提供）： 第一阶段SBIR项目的目标是证明高分辨率真三维（3D）彩色显示器用于医疗数据显示应用的可行性。这样的显示器将极大地改善远程（远程呈现）医学教学、诊断和三维类型的医学数据（CT扫描、MRI扫描、PET扫描、声学扫描等）的查看。显示器将使用宽带（“白色光”，而不是激光）照明，因此不存在设备的眼睛安全问题。虽然目前存在伪3D显示器（通常是立体的，或者一次将一个平面投影到体积显示器上，或者需要护目镜）和至少一个将激光投影到地球仪上的显示器，但是这些都不能在眼睛处重建真正的三维光波。因此，这些显示器都存在各种问题，并且通常是笨拙的并且在使用中不是很令人满意。拟议的研究的目标是生产一个紧凑的，具有成本效益的，3D显示投影仪。 电光元件、照明源和计算速度的最新技术水平已经发展到这样一个程度，（但也具有高风险）创建真正的三维空间是可行的。（全息）显示器，其可用于投影用于医学教学的三维医学图像，辅助不太熟练的人员进行医学诊断，以及在相同或不同领域的医学专家之间通过因特网共享三维医学数据。这个第一阶段SBIR项目将调查硬件和计算的可行性，创造这种全息显示与可用的（虽然国家的最先进的）电光元件和计算资源。预期的结果是3D显示器的可行性论证，沿着概念显示器设计，用于项目第二阶段原型3D显示器的实际设计和建造。虽然风险很高，但这一奋进的成功将是医疗远程呈现和3D数据显示应用的巨大胜利。
