Title (EN) CONTROLLING LENS MISALIGNMENT IN AN IMAGING SYSTEM
(FR) CONTRÔLE DE DÉSALIGNEMENT DE LENTILLES DANS UN SYSTÈME D’IMAGERIE
Abstract:
(EN) An imaging method includes imaging a scene using an imaging system (20), which includes an array (24) of radiation sensing elements, including first sensing elements (40) with symmetrical angular responses and second sensing elements (46, 54, 60, 62) with asymmetrical angular responses, interspersed among the first sensing elements, and optics (22) configured to focus radiation from the scene onto the array. The method further includes processing first signals output by the first sensing elements in order to identify one or more areas of uniform irradiance on the array, and processing second signals output by the second sensing elements that are located in the identified areas, in order to detect a misalignment of the optics with the array.
(FR) Un procédé d’imagerie comprend l’imagerie d’une scène à l’aide d’un système d’imagerie (20) qui comprend un réseau (24) d’éléments de détection de rayonnement, comprenant des premiers éléments de détection (40) avec des réponses angulaires symétriques et des seconds éléments de détection (46, 54, 60, 62) avec des réponses angulaires asymétriques, dispersés parmi les premiers éléments de détection, et un dispositif optique (22) configuré pour focaliser sur le réseau un rayonnement provenant de la scène. Le procédé comprend en outre le traitement de premiers signaux délivrés par les premiers éléments de détection afin d’identifier une ou plusieurs zones de radiance uniforme sur le réseau, et le traitement de seconds signaux délivrés par les seconds éléments de détection, qui sont situés dans les zones identifiées, afin de détecter un désalignement entre le dispositif optique et le réseau.
