Abstract

Additional to the development of 3rd Gen IR modules like dual-band and dual-color devices AIM is focused on IR FPAs with reduced pitch. These FPAs allow manufacturing of compact low cost IR modules with minimum power consumption for state-of-the-art high performance IR systems. AIM has realized full TV format MCT 640x512 mid-wave and long-wave IR detection modules with a 15 μm pitch to meet the requirements of critical military applications like thermal weapon sights or thermal imagers in UAV applications. In typical configurations like a F/4.6 cold shield for the 640x512 MWIR module an NETD < 25 mK @ 5 ms integration time is achieved, while the LWIR modules achieve an NETD < 38 mK @ F/2 and 180 μs integration time. For the LWIR modules FPAs with a cut-off of 9 and 10 μm have been realized. The modules are available either with different integral rotary cooler configurations for portable applications which require minimum cooling power or a new split linear cooler providing long lifetime with a MTTF > 20,000 h as required e.g. for warning sensors in 24/7 operation. The modules are available with an optional image processing electronics providing non-uniformity correction and further image processing for a complete IR imaging solution. A double field of view FLIR for an upgrade of the German Army UAV LUNA has been developed by AIM using the MCT 640x512 MWIR 15μm pitch engine. The latest results and performance of those modules and their applications are presented.
