The rapid development of Air Force technology is in part limited by the timely development and implementation of advanced materials. Sequential, iterative approaches to modeling and experimental testing are no longer adequate, and multi-scale approaches are increasingly common. The overall goal of this proposal is to fully exploit the intrinsic properties of 3D image correlation photogrammetry, a full-field optical test method, in support of accelerated insertion of materials (AIM) programs. Successful accomplishment of the Phase I objectives would provide a strong foundation for development of a fully automated and integrated multi-scale data acquisition and visualization system. The system would be capable of automatically acquiring experimental 3D deformation and strain data and comparing it to model results. Multi-scale for this system would refer to both space and time; fields of view from 2 meters to less than 1 mm, and data acquisition timeframes from days to microseconds. The Trilion Quality Systems team, a developer of optical and machine vision measurement technologies for more than twenty years, has a strong coalition of DoD customers and University Centers of Excellence uniquely organized to support the development of this powerful optical inspection technology to meet the measurement needs of the Air Force and many other potential users.
