Physical Optics Corporation (POC) proposes to develop a unique electro- optic volumetric three dimensional (3-D) display monitor that will enable radiologists, physicians, and surgeons to directly determine the location, size, shape, and distribution of tumors with high geometric and photometric accuracy. The proposed multiplanar volumetric 3-D display is based on two unique electro-optic Components: (l) a high speed VLSI-back plane ferroelectric liquid crystal spatial-light- modulator (FLC-SLM) chip, and (2) an electrically tunable variable focal plane refractive optical element lens. Using these components, a high speed time sequence of tomographic slice images can be projected into space, forming a precisely reconstructed tomogram in a 3-D volume with full physical depth cues. The display will be a very compact, lightweight, and low.power device, with no moving parts, capable of displaying 100 or more data slices in real time from identical or complementary tomographic scans. In Phase I, POC will design a laboratory prototype and demonstrate the feasibility of the proposed concept by integrating our existing 128 x 128 FLC-SLM with a tunable refractive optics Fresnel lens. A set of tomographic slice images will be used to test the performance of the demonstration device. PROPOSED COMMERCIAL APPLICATION: Commercial applications of the EOVTD will be in entertainment (i.e., video games), CAD/CAM, surveillance photogrammetry, training and simulation, air traffic control, and molecular modeling, while the components (FLC-SLM and TROEL) will find applications in advanced projection displays, optical correlators and processors, confocal microscopes, video cameras and space telescopes.

物理光学公司(POC)建议开发一种独特的电子- 光学体积三维(3-D)显示监视器 使放射科医生、内科医生和外科医生能够直接确定 高几何构型肿瘤的位置、大小、形状和分布 和测光精度。提出的多平面体三维 显示器是基于两个独特的光电组件：(L)高 速度超大规模集成电路背平面铁电液晶空间光 调制器(FLC-SLM)芯片，以及(2)电可调可变焦距 平面折射光学元件透镜。使用这些组件， 层析切片图像的速度时间序列可以投影到 空间，在3-D体积中形成精确重建的断层图像 完整的物理深度线索。显示器将是非常紧凑的， 重量轻、功率低的设备，没有移动部件，能够 实时显示100个或更多来自相同或 互补的断层扫描。在第一阶段，PoC将设计一个 实验室样机并论证了建议的可行性 通过将我们现有的128 x 128 FLC-SLM与可调的 折射光学菲涅耳透镜。一组断层切片图像将 用于测试演示装置的性能。 建议的商业应用：EOVTD的商业应用 将用于娱乐(即视频游戏)、CAD/CAM、监控 摄影测量、培训和模拟、空中交通管制和 分子建模，而组件(FLC-SLM和Troel)将找到 在高级投影显示器、光学相关器和 处理器、共焦显微镜、摄像机和空间望远镜。
