  • Patent number: 9234693
    Abstract: An image sensing apparatus includes a focal plane array and a cold shield thermally isolated from the focal plane array. The cryogenic cooling apparatus further includes a first cryocooler assembly comprising a first cold finger thermally coupled to the focal plane array. The first cryocooler assembly is configured to maintain a focal plane array operating temperature. The cryogenic cooling apparatus includes a second cryocooler assembly comprising a second cold finger thermally coupled to the cold shield. The second cryocooler assembly is configured to maintain a cold shield operating temperature that is different from the focal plane array operating temperature.
