FLIR Systems, which has long concentrated on its mature InSb FPA technology has been internally developing Type 2 Superlattice (T2SL) FPAs for use in future products.The company, which has been part of the VISTA consortium, is making use of the InAs/GaSb epitaxial structures that have been developed by JPL and NRL under the VISTA program and grown by IntelliEPI and IQE. It is expected that the company will soon introduce a camera core based on a HOT MWIR 640 x 512 FPA with 15 micron pixels.
Raytheon and Lockheed Martin have signed a contract under which Raytheon will provide the next-generation EO-DAS (Electro-optical-Distributed Aperture System) for the F-35 Joint Strike Fighter. The new system will make use of very large format, small pixel MWIR nBn FPAs developed by Raytheon Vision Systems (Goleta, California).
A breakthrough in the more widespread use of Type 2 Superlattice (T2SL) FPAs is about to occur. One of the largest infrared applications in the U.S. - the EO-DAS (Electro-optical-Distributed Aperture System) for the Lockheed Martin F-35 Joint Strike Fighter - is being upgraded to T2SL FPAs (from the existing large format InSb FPAs).The Air Force anticipates two potential upgrades.

Multi-megapixel infrared imaging at room temperature for wafer-level scalable FPAs at low-cost
Imaging of gas leaks (especially of methane, but also of other gases) has traditionally been done with portable infrared cameras based on cooled InSb and QWIP FPAs. In these, either the FPA spectral response is tuned to the absorption wavelength of the gas of interest or a spectral filter is used in front of it. Alternatively, high-end spectrally selective (Fourier Transform Infrared – FTIR) cameras (also based on cooled FPAs) are used to detect gas leaks with high sensitivity, but at a price premium.
Now, a new generation of innovative uncooled gas sensors are being developed to not just monitor large gas leaks but also act as monitors for small leaks.
Active Protection Systems (APS) for armored vehicles are becoming a necessity as rocket propelled grenades (RPGs) and anti-armor munitions become more effective against even the best armor. In APS systems an incoming round is detected and tracked and a counter munition is fired to destroy the round before it can damage the vehicle.
In the most recent systems, infrared FPAs are being used.

Lockheed Martin is introducing a new pilotage sensor for cargo and utility aircraft. The sensor was recently demonstrated on a UH-1 helicopter at Fort Belvoir, Virginia.
DARPA’s Microsystems Technology Office has awarded four 3-year contracts for the development of near room temperature (or “HOT - High Operating Temperature”) mid-wave infrared focal plane arrays. The FPAs are intended for future use in ground-based threat warning systems.
The U.S. Department of Homeland Security’s Strategic Border Initiative program (SBInet) is shaping up to be a boon for infrared technology. SBInet has two major themes: controlling the border and immigration enforcement.
