Abstract
L'ensemble de détection optique comporte au moins un détecteur optique destiné à être placé dans un plan focal d'un instrument d'observation et un dispositif de contrôle thermique dédié à maintenir le détecteur optique à une température de fonctionnement prédéfinie. Le dispositif de contrôle thermique comporte une platine en céramique supportant le détecteur optique, une cale de réglage de la position du détecteur optique et un radiateur externe. Le dispositif de contrôle thermique comporte en outre un matériau à changement de phase en contact direct avec le détecteur optique, le composant à changement de phase étant logé dans une cavité ouverte de la cale de réglage, sans aucun contact avec la cale de réglage, ni avec la platine en céramique.
