Title (EN) IMPROVED IMAGING METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL D'IMAGERIE AMÉLIORÉS
Abstract:
(EN) A method of correcting errors in the output of an image detector is disclosed. The method comprises measuring an output signal (Vm) of a capacitor (Csh) holding a voltage corresponding to a signal detected by the image detector;comparing the value of output signal (Vm) to the value of the previously measured output signal (Vm-1) of the capacitor (Csh);calculating the error in the output signal (Vm) using a predetermined correction factor and the difference between the value of the output signal (Vm) and the value of the previously measured output signal (Vm-1); and providing a corrected output value (Vcrt) in accordance with the calculated error. Detectors, methods of calibrating detectors, image correction apparatus and guidance systems comprising the detectors are also disclosed.
(FR) L'invention concerne un procédé qui permet de corriger des erreurs dans la sortie d'un détecteur d'image. Le procédé consiste à mesurer un signal de sortie (Vm) d'un condensateur (Csh) maintenant une tension correspondant à un signal détecté par le détecteur d'image ; à comparer la valeur du signal de sortie (Vm) à la valeur du signal de sortie mesuré précédemment (Vm-1) du condensateur (Csh) ; à calculer l'erreur dans le signal de sortie (Vm) à l'aide d'un facteur de correction prédéterminé et de la différence entre la valeur du signal de sortie (Vm) et la valeur du signal de sortie mesuré précédemment (Vm-1) ; à fournir une valeur de sortie corrigée (Vcrt) conformément à l'erreur calculée. L'invention concerne également des détecteurs, des procédés de calibrage des détecteurs, un appareil de correction d'image et des systèmes de guidage comprenant les détecteurs.
