Title (EN) INFRARED DETECTION AND IMAGING DEVICE WITH NO MOVING PARTS
(FR) DISPOSITIF D'IMAGERIE ET DÉTECTION INFRAROUGE SANS PIÈCES MOBILES
Abstract:
(EN) A device images radiation from a scene. A detector is sensitive to the radiation in a first wavelength band. A lens forms an image of the scene on the detector. A filtering arrangement includes two sets of radiation absorbing molecules. A control unit switches the filtering arrangement between two states, in the first state, all of the radiation in the first wavelength band is transmitted to the detector, in the second state, the radiation in a second wavelength band within the first wavelength band is absorbed by the radiation absorbing molecules. The control unit synchronizes the switching of the filtering arrangement with the detector. Each pixel of the image formed on the detector includes two signals. The first signal includes information from the scene radiation in the first wavelength band. The second signal excludes information from the scene radiation absorbed by the filtering arrangement in the second wavelength band.
(FR) La présente invention concerne un dispositif d'imagerie du rayonnement provenant d'une scène. Un détecteur est sensible au rayonnement dans une première bande de longueurs d'onde. Une lentille forme une image de la scène sur le détecteur. Un agencement de filtrage comprend deux ensembles de molécules d'absorption de rayonnement. Une unité de commande commute l'agencement de filtrage entre deux états : dans le premier état, tout le rayonnement dans la première bande de longueurs d'onde est transmis au détecteur et, dans le second état, le rayonnement dans une seconde bande de longueurs d'onde comprise dans la première bande de longueurs d'onde est absorbé par les molécules d'absorption de rayonnement. L'unité de commande synchronise la commutation de l'agencement de filtrage avec le détecteur. Chaque pixel de l'image formée sur le détecteur comprend deux signaux. Le premier signal comprend des informations de rayonnement de scène dans la première bande de longueurs d'onde. Le second signal exclut les informations de rayonnement de scène absorbées par l'agencement de filtrage dans la seconde bande de longueurs d'onde.
