Abstract

L'invention concerne un système et un procédé permettant de focaliser des détecteurs à infrarouge fonctionnant à des températures cryogéniques. Le système décrit dans cette invention comprend un capteur (10) conçu pour détecter l'énergie électromagnétique, lequel capteur comprend un premier détecteur (14) fonctionnant dans une première plage de températures, et un nombre prédéterminé de détecteurs auxiliaires (12) fonctionnant dans une seconde plage de températures. Les détecteurs auxiliaires (12) sont adjacents au premier détecteur (14) et ils sont placés dans le même plan optique que ce dernier. Dans le mode de réalisation susmentionné, l'énergie est une lumière infrarouge ou une lumière visible, la première plage de températures étant une plage de températures cryogéniques, et la seconde plage de températures étant une plage de températures ambiantes. Le premier détecteur (14) est un vidéo-détecteur réseau et les détecteurs auxiliaires (12) sont des réseaux de détecteurs non refroidis. Dans un mode de réalisation privilégié, le vidéo-détecteur réseau (14) et les détecteurs non refroidis (12) sont disposés sur un même substrat. Le capteur (10) décrit dans cette invention peut être utilisé pour focaliser un système optique à des températures cryogéniques. Le procédé décrit dans cette invention consiste à envoyer de l'énergie dans le capteur (10) par l'intermédiaire du système optique à des températures ambiantes, puis à ajuster la position dudit capteur (10) jusqu'à réception par les détecteurs auxiliaires (12) d'un éclairement maximum. Ce mode de réalisation permet de positionner le plan focal du système à des températures ambiantes. Le positionnement du plan focal à des températures cryogéniques peut être calculé au moyen du positionnement du plan focal à des températures ambiantes et d'un modèle de caractéristiques thermiques du système.A system and method for focusing infrared detectors operating at cryogenic temperatures is provided. The system described in this invention includes a sensor (10) adapted to detect electromagnetic energy, which sensor includes a first detector (14) operating in a first temperature range, and a predetermined number of auxiliary detectors (12) operating in a second temperature range. The auxiliary detectors (12) are adjacent to the first detector (14) and are placed in the same optical plane as the latter. In the aforementioned embodiment, the energy is infrared light or visible light, the first temperature range being a cryogenic temperature range, and the second temperature range being an ambient temperature range. The first detector (14) is a network video detector and the auxiliary detectors (12) are networks of uncooled detectors. In a preferred embodiment, the network video detector (14) and the uncooled detectors (12) are arranged on the same substrate. The sensor (10) described in this invention can be used to focus an optical system at cryogenic temperatures. The method described in this invention consists in sending energy into the sensor (10) via the optical system at ambient temperatures, then in adjusting the position of said sensor (10) until reception by the auxiliary detectors ( 12) maximum illumination. This embodiment makes it possible to position the focal plane of the system at ambient temperatures. The positioning of the focal plane at cryogenic temperatures can be calculated by means of the positioning of the focal plane at ambient temperatures and a model of thermal characteristics of the system.
