(EN) ADVANCED OPTICS FOR IRST SENSOR
(FR) OPTIQUE AVANCÉE POUR CAPTEUR DE VEILLE ET POURSUITE PAR INFRAROUGE
Abstract
(EN)
An optical sensor system having an extended elevation field of view and in which the optics are configured around an all-reflective four-mirror reimaging anastigmat used for afocal foreoptics and an all-reflective five-mirror reimaging anastigmat used for imaging optics. One example of an optical sensor system includes afocal foreoptics configured to receive and collimate electromagnetic radiation, the afocal foreoptics including an all- reflective, reimaging four-mirror anastigmat, an imaging detector, focal imaging optics positioned between the afocal foreoptics and the imaging detector and configured to receive the collimated beam of electromagnetic radiation from the afocal foreoptics and to focus the beam of electromagnetic radiation onto the imaging detector, the focal imaging optics including a reimaging five-mirror anastigmat, wherein a field of view of the system is determined at least in part by a combination of the afocal foreoptics and the focal imaging optics and covers at least 5 degrees in elevation.

L'invention concerne un système de capteur optique ayant un champ de vision d'élévation étendu et dans lequel les éléments optiques sont configurés autour d'un anastigmate de ré-imagerie à quatre miroirs à réflexion totale utilisé pour une optique avant afocale et un anastigmate de ré-imagerie à cinq miroirs à réflexion totale utilisé pour une optique d'imagerie. Un exemple d'un système de capteur optique comprend une optique avant afocale configurée pour recevoir et collimater un rayonnement électromagnétique, l'optique avant afocale comprenant un anastigmate de ré-imagerie à quatre miroirs à réflexion totale, un détecteur d'imagerie, une optique d'imagerie focale positionnée entre l'optique avant afocal et le détecteur d'imagerie et configurée pour recevoir le faisceau collimaté de rayonnement électromagnétique provenant de l'optique avant afocale et focaliser le faisceau de rayonnement électromagnétique sur le détecteur d'imagerie, l'optique d'imagerie focal comprenant un anastigmate de ré-imagerie à cinq miroirs, un champ de vision du système étant déterminé au moins en partie par une combinaison de l'optique avant afocale et l'optique d'imagerie focale et couvrant au moins 5 degrés en élévation.
