9529779 Aye This Small Business Innovation Research Phase II project is to develop a new volumetric three-dimensional (VTD) display based on the switchable binary optical element (SBOE) concept. Current direct view volumetric displays have limitations in their performance due to mechanical movement of the display screens, which can be overcome in the proposed VTD display. In this concept, a 2-D array of surface printed binary optical elements (BOEs) are coated with a rapidly switchable Ferro- electric liquid crystal layer. A stack of these arrays form the volume medium of the display. Each BOE, which forms a volume pixel (voxel) element, can be rapidly switched on and off while a 3 color (RGB) low power laser beam is scanned across the display volume. When in an unswitched state, the medium will be transparent. while in a switched state. the scanning laser beam will be diffracted and diffused into a cone shape from the switched voxel elements. In order to produce a 3D image, the scanned laser beam is modulated while scanned over the BOE plane. It is anticipated that this research will result in a real-time flicker-free 3D volume display prototvpe without any moving parts. The proposed VTD system will be extremely valuable for true 3D display technology. Commercial applications of this VTD technology will be in entertainment (ie, video games), medical imaging, CAD/CAM, surveillance photogrammetry, training and simulation, air traffic control, molecular modeling, telerobotics and cockpit or shipboard displays.

这个小企业创新研究二期项目是基于可切换二元光学元件（SBOE）概念开发一种新的体积三维（VTD）显示器。由于显示器的机械运动，目前的直视体积显示器在性能上有局限性，这可以在拟议的VTD显示器中克服。在这个概念中，二维表面印刷二元光学元件（BOEs）阵列被涂上一层快速切换的铁电液晶层。这些阵列的堆叠形成了显示器的体积介质。每个BOE构成一个体积像素（体素）元素，当3色（RGB）低功率激光束扫描整个显示体积时，可以快速打开和关闭。当处于未开关状态时，介质将是透明的。当处于开关状态时。扫描激光束将从被切换的体素元素衍射并扩散成锥形。为了产生三维图像，扫描的激光束在BOE平面上扫描时被调制。预计这项研究将产生一个实时无闪烁的3D体积显示原型，没有任何移动部件。所提出的VTD系统对于真正的3D显示技术将是非常有价值的。这项VTD技术的商业应用将在娱乐（即视频游戏）、医疗成像、CAD/CAM、监视摄影测量、训练和模拟、空中交通管制、分子建模、遥控机器人和驾驶舱或船上显示等领域。
