Sofradir demonstrates compact mid-TV format dual-band IR detector array

At this week’s SPIE Defense and Security Symposium 2007 in Orlando, FL, USA, Sofradir of Veurey-Voroize, near Grenoble, France is conducting a video-camera demonstration of its new Janus compact mid-TV format dual-band staring snapshot 320x256 short-wave (SW) and mid-wave (MW) infrared focal plane assembly (IRFPA), which operates in bands I (1-3 microns) and II (3-5 microns). Such detectors are in demand for decisive day and night vision in the most severe battlefield conditions such as air-to-air missiles and missile warning systems.

Sofradir developed Janus in cooperation with partnering research center CEA-LETI-MINATEC (also of Grenoble) using its newly optimized, stable, low-defect-density photovoltaic mercury cadmium telluride (MCT or HgCdTe) MBE technology. To meet different mechanical and cooling system needs, the dual-band IR detector comes in various long-vacuum-life Dewar and cooler configurations.

The progress to dual-band IR detectors matches growing interest from the military sector for more complex features in a large-format IR detector that improve target identification, signal recognition and clutter rejection (which reduces atmospheric perturbation).
