Abstract
This paper provides an overview of the recent DRS RSTA, Inc. (DRS) Vanadium Oxide (VOx) uncooled focal plane arrays (UFPA), sensor electronics, and camera development activities. Presently, DRS UFPAs consist of 25 μm and 17 μm pixel pitch detectors in 320x240 and 640x480 formats. Under the Army NVESD sponsored 17 μm Large Format Uncooled FPA Development program and internal projects, DRS has developed a 17 μm pitch 1024x768 UFPA product (U8000). The 17 μm pixel pitch UFPAs provide sensor systems with significant size, weight, and power (SWaP) savings as well as cost reductions over the 25 μm pixel pitch counterparts. There is a growing demand to transition current products to the 17 μm pixel technologies. For example, next generation military systems such as thermal weapon sights (TWS), enhanced night vision goggles (ENVG), driver viewer enhancers (DVE) and unmanned aerial vehicle (UAV) infrared (IR) surveillance sensors all called for the 17 μm pixel technologies. To meet market demand, DRS has improved its production facilities to accommodate 17 μm pixel detector manufacturing. In conjunction with these efforts, DRS has also developed a family of signal processing electronics based on a new FPGA architecture for various sensor modules and cameras that can be incorporated into commercial OEM products as well as DoD weapon systems. Under the DARPA funded AWARE Multiband (formerly DUDE) program, DRS and Goodrich Sensors Unlimited, Inc are collaborating on the development of a single, integrated, twocolor detector by combining the VOx microbolometer (8-14 μm) and InGaAs (0.4 -1.6 μm) detectors into a single focal plane array. The first AWARE Multiband dual mode focal plane array fabrication is now underway.
