Title (EN) RAY CORRECTION APPARATUS AND METHOD
(FR) APPAREIL ET PROCEDE DE CORRECTION DE RAYONS
Abstract:
(EN) In a detector system for receiving incoming electromagnetic radiation having a range of chief ray angles (CRAs) that is limited by a stop of the imaging optics, an improvement includes a corrective element that cooperates with imaging optics to ensure that chief rays over the range of CRAs fall within a cone of acceptance angles of the detector. The corrective element may be a tilted lenslet, a diffractive element, a refractive element, a discretized refractive element or a subwavelength structure. A detector system collects a range of chief rays from imaging optics. The system includes an array of detectors, each having a cone of acceptance angles, and a corrective element having one of: an array of lenslets including at least one tilted lenslet; a diffractive element; a refractive element; a discretized refractive element; and subwavelength structures. The corrective element redirects each chief ray to within the cone of acceptance angles.
(FR) L'invention concerne un système de détecteur permettant de recevoir un rayonnement électromagnétique entrant comprenant une gamme d'angles de rayons de champ (CRA) limitée par une butée d'éléments optiques d'imagerie et dans lequel une amélioration consiste en un élément correctif coopérant avec les éléments optiques d'imagerie de manière à garantir que les rayons de champ sur la gamme de CRA tombent dans des angles d'un cône d'admission du détecteur. L'élément correctif peut être une lentille inclinée, un élément de diffraction, un élément de réfraction, un élément de réfraction discrétisé ou une structure de sous-longueurs d'ondes. Le système de détecteur recueille une gamme de rayons de champ à partir des éléments optiques d'imagerie. Le système comprend un réseau de détecteurs comprenant individuellement des angles du cône d'admission et un élément correctif comprenant un élément parmi: un réseau de lentilles comprenant au moins une lentille inclinée; un élément de diffraction ; un élément de réfraction, un élément de réfraction discrétisé; et des structures de sous-longueurs d'ondes. L'élément correctif redirige chaque rayon de champ dans les angles du cône d'admission.
