Abstract:

Many Army applications, such as driver vision enhancement DVE, rifle sights, seekers, physical security, target acquisition, and fire control, would benefit from affordable, passive uncooled infrared IR sensor options. The main considerations for uncooled IR sensors are cost, weight, and power. We have begun a three-year effort to develop a novel approach to the fabrication of uncooled IR focal-plane array FPA detectors using bio-inspired, low-temperature, multimetallic perovskite nanoparticle deposition, direct-write digitally-scripted laser phase conversion, and MEMS fabrication and optimization techniques. Success is contingent on fully characterizing the perovskite films and resolving basic materials issues during the first year of this project.
