Ultraviolet/Infrared Detectors for Active Protection

The ARMY needs active protection using a UV and IR dual band focal plane array (FPA) to detect and track hostile fire so that targets can respond and avoid incoming rounds. The objectives of this effort are to determine the requirements of an uncooledUV/IR FPA for active protection and demonstrate feasibility of integrating UV and IR detector arrays with the readout integrated circuit (ROIC). In this FPA approach the UV and IR detector arrays are grown on the ROIC and monolithically interconnected tothe ROIC without hybrid bump bonds. Specific tasks are to determine the requirements for active protection, grow UV structures on Si wafers and ROICs, fabricate UV device structures on Si wafers and ROICs, and provide a monolithic dual band process.Dualband UV/IR arrays would primarily benefit military applications. However separate uncooled LWIR and UV arrays are attractive for analysis of products and processing, guidance of automobiles, navigation at sea, unmanned aerial vehicles, search and rescue,fire detection and containment, surveillance systems for drug traffic and border control, and rifle night sights.
