Title (EN) SYSTEM AND METHOD FOR ATHERMAL OPERATION OF A FOCAL PLANE ARRAY
(FR) SYSTÈME ET PROCÉDÉ POUR FONCTIONNEMENT ATHERMIQUE D'UN RÉSEAU EN PLAN FOCAL
Abstract:
(EN) A method includes determining a signal current based on an average current associated with one or more detectors. The method also includes determining a strip voltage based on the signal current. The method further includes biasing a strip resistance with the strip voltage. The biasing of the strip resistance creates a strip current. The method additionally includes biasing a detector array with a detector voltage. The biasing of the detector array creates a detector current. The method also includes determining levels of incident radiation from a scene based on the strip current and the detector current.
(FR) L'invention concerne un procédé comportant une étape consistant à déterminer un courant de signal sur la base d'un courant moyen associé à un ou plusieurs détecteurs. Le procédé comporte également une étape consistant à déterminer une tension de bande sur la base du courant de signal. Le procédé comporte en outre une étape consistant à polariser une résistance de bande par la tension de bande. La polarisation de la résistance de bande crée un courant de bande. Le procédé comporte de plus une étape consistant à polariser un réseau de détecteurs par une tension de détecteurs. La polarisation du réseau de détecteurs crée un courant de détecteurs. Le procédé comporte également une étape consistant à déterminer des niveaux de rayonnement incident provenant d'une scène sur la base du courant de bande et du courant de détecteurs.
