Dual-color InAs/GaSb superlattice infrared imagers

High-performance dual-color infrared imaging systems have been realized with InAs/GaSb type-II superlattices. The detectors offer a spatial resolution of 288×384 pixels with a simultaneous, co-located detection at 3-4 μm (blue channel) and 4-5 μm (red channel), respectively. Against a 300 K backgrou...

Zusammenfassung:High-performance dual-color infrared imaging systems have been realized with InAs/GaSb type-II superlattices. The detectors offer a spatial resolution of 288×384 pixels with a simultaneous, co-located detection at 3-4 μm (blue channel) and 4-5 μm (red channel), respectively. Against a 300 K background, a thermal resolution of 18 mK in the blue and 10 mK in the red channel has been achieved. The detectors are well suited for low-false alarm imaging of hot carbon dioxide signatures on a millisecond time scale.
