Updateable 3D Display Using Large Area Photorefractive Polymer Devices

Command and control battle maps and mission planning can be greatly enhanced by the representation of the battlefield in 3 dimensions. Showing perspective views, depth and occlusions allows for a better understanding of the situation, and assists in avoiding error when interpreting the terrain. Such maps already exist and are in use, but are based on permanent holographic media that cannot be refreshed. We propose to develop a large (1ft x 1ft), full color, updatable holographic 3D display using a photorefractive polymer device as recording element. With a refreshing rate of a few tens of seconds and highly realistic 3D holograms, this device can be updated with new information for situational awareness in near real time. With respect to dual use applications, this technology can be used for medical imaging and advertisement. BENEFIT: The large-area display enables command personnel to efficiently monitor changes in 3D and in real time, greatly increasing situational awareness, improving response time, and reducing erroneous targeting, among other benefits. Achievement of the demanding goals required for this application will further ensure broad application of PR polymers. The developed technology will have disruptive dual use applications in addition to the military applications. The functionalities proposed here will bring PR polymer 3D display devices a step closer to applications of these devices in defense, aircraft design and manufacturing, surgery, advertising and training.
