Abstract

Raytheon IRCOE has developed a family of uncooled, microbolometer FPAs. These FPAs have been designed to address commercial and high-performance military applications. The SB-151 is a high-sensitivity 320 X 240 FPA with 50 micrometers pixels. The SB-151 FPA has been fabricated with several microbolometer pixel designs that allow optimization of either sensitivity or response time. Noise equivalent temperature difference (NETD) values as low as 8.6 mK have been measured for the SB-151 FPAs with f/1 optics. NETD values less than 25 mK have been measured for FPAs with thermal time constants of approximately 18 msec.
