The UK’s Albion program for developing 3rd Gen FPAs has gone into Phase 2 with the award by the UK MOD of a £5.8 million (approximately $10.6 million) three-year contract to prime contractor Selex Sensors and Airborne Systems.
The fabrication of mercury cadmium telluride (MCT) FPAs by MOVPE (Metal Organic Vapor Phase Epitaxy) continues to make rapid progress. Most recently, both Selex Sensors & Airborne Systems, S&AS and QinetiQ have achieved new performance levels with dual-band (MW/LW) FPAs.
QinetiQ has been awarded a two-year, $5 million research contract by DARPA in support of its Large Area Coverage Optical Search While Track and Engage (LACOSTE) program. Under LACOSTE, extremely-wide field-of-view coded aperture imaging technology will be used to support single sensor day/night persistent tactical surveillance of all moving vehicles in a large urban battlefield.
SELEX Sensors & Airborne Systems is moving ahead in the UK’s Albion program for the development of 3rd Gen FPAs based on mercury cadmium telluride (MCT) FPAs grown by MOVPE (Metal Organic Vapor Phase Epitaxy). After experimenting with both GaAs and GaAs:Si (GaAs on silicon) substrates, researchers have settled on the GaAs substrates because of the lower defect levels and the better stability of defect levels at storage temperatures to 100ºC.
