We compare measurements and modeling of 27 and 63 MeV proton-induced transients in a large-format HgCdTe long wavelength infrared (LWIR) focal plane assembly operating at 40 K. Charge collection measurements describe very limited diffusion of carrier

The results of total ionizing dose and proton fluence characterization of hybrid Si P-i-N focal plane arrays are reported. The focal plane arrays consist of a silicon P-i-N detector array bump bonded to 128 x 128 CMOS readout integrated circuit (ROIC

Long wavelength, infrared focal plane arrays (IRFPAs) fabricated with arsenic doped silicon (Si:As), impurity band conduction (IBC) detectors are being utilized in astronomical applications. In these systems, long integration times and/or the co-addi

A system for measuring the average relative spectral response of long wavelength infrared focal plane arrays (IRFPA) has been developed. Typically, the spectral response of sister detectors, fabricated on the same wafer as the FPA detectors are chara

A radiometric characterization of a Si:As impurity band conduction hybrid array has been performed. The characterization included measurements of the responsivity and noise as functions of detector bias, photon irradiance, and integration time. Conve

Quantum-well infrared photodetectors (QWIPs) are trapping- mode photodetectors, and it is trapping that leads to an inherent prob- lem: QWIPs' responsivity can be background-dependent under low- background conditions. We have determined that the sour
