Holographic Video Display Using Novel Guided-wave Scanning System
ABSTRACT: TIPD, LLC proposes to design and construct a 3D visualization system that would implement a 3D database capable of ingesting, conflating, and aligning a wide range of static and dynamic data. The system will implement a massively parallel computation and display engine capable of generating fringe information and directly"writing"fringes at video rates. A novel display system employing acousto-optic modulators and electro-optic phased array scanning will generate holographic images and optical wavefronts which provide the operator with a full set of visual clues. This approach can be scaled to larger displays with higher angular resolution based upon the roadmaps of the underlying components. The proposed system will address the shortcomings of the current technologies by providing improved 3D visualization tools to assist the operator in critical situations such as deconfliction, line-of-sight analysis, and satellite control. Current 3D displays cannot provide the level of detail and comfort needed because the displays contain unacceptable visual artifacts, absence of full parallax, require special headgear, and induce nausea in many users. The current visualization systems also do not have the capability to fuse static digital data with incoming LIDAR or video or allow the analyst to view the battles space form arbitrary points-of-view BENEFIT: The proposal will enable a number of critical holographic display applications based on its here-to-fore undelivered combination integrated 3D database, massively parallel computation engines and the packing of the system optimized for small size, weight, and power (SWaP) requirements. The holographic system will deliver a true holographic display generating a light field with vergence and accommodation clues aligned. Currently available 3D displays cannot provide the level of detail and comfort needed because the displays contain unacceptable visual artifacts, do not provide full parallax, require special headgear, and induce nausea in many of the users. The benefits of the improved display system allow will intelligence analysts to assist war fighters in critical situations such as deconfliction, line-of-sight analysis, and air space and satellite control. The system design can be extended to dual use applications in medicine by allowing radiologists to view holographic displays of CT and MRI images, in scientific visualization for 3D engineering drawings and multidimensional data display. Other dual use applications include visualization of cultural heritage sites, holographic special effects for the entertainment industry, and holographic teleconferencing (telepresence) applications.
