Raytheon Vision Systems (Goleta, California) is in the fortunate position of having the largest portfolio of advanced infrared detectors in the world, including mercury cadmium telluride (MCT), InSb, InGaAs, uncooled VOx microbolometers and others. Recently, the company’s III-V T2SL (Type II Superlattice)/nBn detectors have also reached a level of maturity that enabled Raytheon to win the contract for the next-generation Distributed Aperture System (DAS) for the F-35 Joint Strike Fighter.
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
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.

Imaging lead salt FPAs are poised to make a comeback for niche military applications after having almost disappeared from view.
Last month the U.S. Army awarded Northrop Grumman (Rolling Meadows) a 20 month $6.1 million contract to continue development on a two-color uncooled, midwave, Lead Selenide (PbSe) Passive Infrared Cueing System (PICS).
L-3 Communications has signed an agreement to acquire Northrop Grumman's Electro-Optical Systems (EOS) business for $175 million in cash. The EOS business had 2007 revenues of approximately $190 million in night vision goggles, weapons sights, driver viewers, image intensifier tubes and applied optics products.
Northrop Grumman is preparing its latest Litening AT targeting pod for flight tests in November. The new Litening AT (currently called 4th Gen Litening) makes use of a 1024 x 1024 InSb FPA (18 µm pixels) detector module (made by FLIR/Indigo), a 1024 x 1024 CCD visible sensor, a new dual-band laser designator and range finder, laser spot tracker and infrared laser marker.
The U.S. Coast Guard’s SeeCoast port surveillance program is adding infrared and electro-optic cameras to the Port Security and Monitoring System so as to detect, classify and track vessels.
