Quantum Tech Advances US Air Force Surveillance Satellites
(I-HLS.com) The US Air Force has been running a program named FORTRESS, Focused Opportunity Reaching Toward Reliable Electro-Optic Strategic Sensors, designed for developing, growing and fabricating large-format HgCdTe (mercury cadmium telluride) infrared focal plane array detectors with ultra-low noise and high quantum efficiency. These devices will be able to survive bombardment by space radiation, as well as laser attacks.
The FORTRESS program involves development for military space applications, focusing on the design, growth, and fabrication of HgCdTe ultra-low-noise and high-quantum-efficiency detector arrays in large physical formats. FORTRESS will advance scientific knowledge, growth, processing, and characterization capability in low-noise infrared sensor chip assemblies (SCAs) for national strategic space applications, such as electro-optical surveillance satellites.
