Abstract

ABSTRACT: Today s analysts need improved 3D visualization tools to assist in critical situations such as deconfliction, line-of-sight analysis, air space and satellite control. 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 proposed system has demonstrated the technical feasibility of several technologies that can address the shortcomings of the current displays. The Phase I program demonstrated a massively parallel computation and display engine capable of generating fringe information and directly writing the fringes using novel display system. The solid-state display system employs acousto-optic modulators for horizontal deflection and electro-optic phased array to generate the vertical deflection. This technique generates true full parallax holographic images and provides the operator with a full set of visual clues. The system is based on COTS graphics processors (GPUs) and easy to fabricate lithium niobate materials allowing the system to be optimized for small size, weight, and power (SWaP) requirements. This novel approach can be scaled to larger video-rate displays, with higher angular resolution based upon the roadmaps of the underlying components. BENEFIT: The proposal will enable a number of critical holographic display applications based on its here-to-fore undelivered combination of an integrated 3D database, massively parallel computation engine and novel scanning technology. The system is based on COTS graphics processors (GPU) and easy to fabricate lithium niobate materials allow the system to be 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.
