This paper presents how resistive bolometers, which are the elementary parts of almost all existing infrared imaging systems, can be upgraded into smart-sensors. The intelligence distributed at the pixel level compensates some intrinsic limitations of these passive sensors. It also comes up with new features called smart-functions and enables enhanced performance.
RÉSUMÉ
Dans le contexte de l’imagerie infrarouge, cet article présente comment les bolomètres résistifs, constituants élémentaires de la quasi-totalité des imageurs actuels, peuvent être améliorés en des capteurs infrarouge intelligents. L’intelligence ainsi distribuée au niveau de chacun des pixels permet de compenser certaines des limitations intrinsèques de ces détecteurs passifs. Elle apporte aussi à ce type d’imageurs de nouvelles fonctionnalités qualifiées d’évoluées et ouvre la perspective de performances accrues.
