Abstract

We compare several key infrared detector technologies versus operating temperature and background flux via hybrid FPA test at operating temperatures from 32.5 K to room temperature and photon backgrounds from mid-10⁵ to approximately equal to 10¹⁷ photons/cm²-sec. The detector materials include photovoltaic (PV) HgCdTe/Al₂O₃, PV HgCdTe/CdZnTe, photoconductive (PC) GaAs/AlGaAs quantum well infrared photodetector (QWIP) and PV InGaAs/InP; the device sizes range from 64 multiplied by 64 to 1024 multiplied by 1024.
