AbstractTarget discrimination capability can be greatly improved by contrasting the spectral energy content of the target against the background radiation. For fast target discrimination, Boston Applied Technologies proposes to develop a composite dynamic optical filtering technology for imaging arbitrary spectral responses. It can perform not only sequential wavelength-by-wavelength tuning, but also reconfigure the combinations of wavebands (even complicated spectral profile over a broad range) at microseconds intervals. Basic concepts of this technology have been experimentally demonstrated in Phase I, which included wavelength-to-wavelength tuning and sophisticated spectral profile reconfiguration. Working range of this device covers from visible to mid-infrared (up to 8.0 micron). In this Phase II proposal, we will capitalize on the Phase I success and develop a mid-IR composite focal plane array with rapid reconfiguration ability with arbitrary spectral response. Several innovative technologies will be implemented, including the synthesis technique for high-performance electro-optical materials, the software and hardware for composing arbitrary transmission curves, as well as the algorisms for fast non-linear regression.
