Abstract
(EN)
An infrared imaging device is disclosed. Shut-off means (40) is closable and openable, and shuts off infrared radiation incident on an optical system (20) when it is in a close state. While the infrared imaging device is imaging, the shut-off means (40) is set in an open state, and the optical system (20) forms an infrared image of an object (70) on an infrared sensor (10) by focusing infrared radiation radiated from the object (70). The infrared sensor (10) outputs a signal corresponding to the amount of infrared radiation received by each pixel. Correction means (30) corrects the sensitivity variations of pixels and the effect of infrared radiation from the optical system (20). While the infrared imaging (40) device is calibrated, the shut-off means is set in a closed state, and correcting means (30) determines a correction coefficient for correcting the variation of the amount of infrared radiation from the optical system (20) by using the output of the infrared sensor (10) imaging the shut-off means (40).

L'invention concerne un dispositif d'imagerie aux rayons IR. Un système d'obturation (40) pouvant s'ouvrir et se refermer bloque le rayonnement infrarouge dans un système optique (20) lorsqu'il est dans un état fermé. Lors de la prise d'images par le dispositif d'imagerie IR, le système d'obturation (40) est dans un état ouvert, et le système optique (20) forme une image infrarouge d'un objet (70) sur un capteur infrarouge (10) par la focalisation du rayonnement infrarouge émis par l'objet (70). Le capteur infrarouge (10) émet un signal correspondant à la quantité du rayonnement infrarouge reçu par chaque pixel. Un système de correction (30) corrige les variations de sensibilité des pixels ainsi que l'effet du rayonnement infrarouge depuis le système optique (20). Lors de l'étalonnage du dispositif infrarouge (40), on met le système d'obturation dans un état fermé, et le système de correction (30) détermine un coefficient de correction pour corriger la variation dans la quantité du rayonnement infrarouge provenant du système optique (20) en utilisant la sortie du capteur infrarouge (10) qui prend l'image du système d'obturation (40).
