Abstract: An infrared detector has its sensor chip assembly (10, 12, 14) cooled to a relatively low temperature required for its operation, whereas a preamplifier (56) required to be positioned close to the sensor chip assembly and which generates considerably more heat than does the sensor chip assembly, is thermally isolated from the sensor chip assembly and its support (16) and is cooled to a higher temperature to thereby significantly reduce the power dissipated to the coldest refrigerator stage (90).

Abstract: Les puces (10, 12, 14) d'un détecteur à infrarouge sont refroidies à une température relativement basse, ainsi que l'exige le fonctionnement de celui-ci, tandis qu'un pré-amplificateur (56) devant être positionné à proximité des puces et produisant considérablement plus de chaleur que les puces, est isolé thermiquement du détecteur et de son support (16), et est refroidi à une température plus élevée pour réduire substantiellement l'énergie perdue qui est transmise à la partie la plus froide du réfrigérateur (90).
