Adaptive Projection Screen

ABSTRACT: The US Air Force relies on realistic projection display systems to simulate operational environments for training of JTAC personnel. One current limitation is that the projection screen materials are passive and do not allow reflectance to be adjusted for day/night difference or to accommodate night vision. In this SBIR program, Triton working with a leader in the projection training display industry proposes to demonstrate a novel adaptive screen material with the desired adjustable reflectance across the VIS and NIR. The material will be bendable with a radius of curvature>1m permitting large domes to be constructed. Phase I will demonstrate and test a prototype screen, measure its optical properties and evaluate multiple modes of functionality. In Phase II we propose to build a full size adaptive dome and demonstrate it onsite at an Air Force facility. BENEFIT: The ability to gradually transition the gain of the projection material would accomplish the same benefit afforded by the insertion of optical filters, but over a much greater range of bright to dark, and would enable uninterrupted training. The result will be a more realistic immersive training experience, especially during the critical yet difficult to simulate dawn/dusk and night-time periods. In addition to the Air Force training requirement, the proposed Triton adaptive screen would find commercial uses for training and simulation by air traffic controllers, police and fire, as well as for sports training, gaming and entertainment.
