Focal plane detectors for the WISE 12- and 23-μm bands
2007
DRS Sensors & Targeting Systems, under contract to the Space Dynamics Laboratory of Utah State University, is
providing the focal plane detector system for NASA's Wide-field Infrared Survey Explorer (WISE). The focal plane
detector system consists of two mercury cadmium telluride (MCT) focal plane module assemblies (FPMAs), two arsenic
doped silicon (Si:As) Blocked Impurity Band (BIB) FPMAs, electronics to drive the FPMAs and report digital data from
them, and the cryogenic and ambient temperature cabling that connect the FPMAs and electronics. The MCT and Si:As
BIB focal plane arrays (FPAs) utilized in the WISE FPMAs are both megapixel class indium-bump hybridized devices
fabricated by Teledyne Imaging Systems and DRS Sensors & Targeting Systems, respectively. This paper reports
performance of the WISE Si:As BIB FPAs that are used for the WISE 12- and 23-μm wavelength bands.
