A More Compact Infrared Detector for Tomorrow's Systems

http://www.bulletins-electroniques.com/actualites/63935.htm

Sofradir working with ONERA (France's government aerospace research laboratory) has engineered a new infrared detector with integrated optics, which was presented at the SPIE Defense, Security & Sensing symposium last April in Orlando, Florida. Although the design is based on a standard Sofradir small pitch video quality infrared IR detector (640 x 512, 15-micron pixel pitch VGA format), what is new is the integration of an optical lens alongside the IR detector, a feat that requires the control of all the IR detector operating and performance parameters. As a result, the IR detector can produce a standalone image without the use of any other associated optics. The company says the demonstration IR detector provides a very large field of view that is well suited to security surveillance operations. This is the first time that a European company has demonstrated the feasibility of integrating optics into a cooled IR detector.

Sofradir says that the new integrated IR detector could lower the amount of optics and electronics in an IR imaging system by about one-third. For IR camera makers, it offers the potential of halving the size of future IR systems. "At present, with the IR detector, we have been able to demonstrate the feasibility of integrating optics, but it can definitely clear the way for other security applications for cooled IR detectors," said Sofradir Vice President in charge of R&D and Technologies Philippe Tribolet.
