this paper indicates the state of progress of advanced infrared detection arrays in the world. This presentation is focused on high-performance cooled detectors i.e. CdHgTe photovoltaic arrays (which are more particularly emphasized), InSb detectors, PtSi Schottky barrier diode arrays, extrinsic silicon photoconductors and 111-V multi-quantum well detectors. It is shown that interest may be focused on parameters other than the intrinsic detector performance alone. Future trends concerning the technologies are briefly presented. A more detailed description of the CEA-LETI-Laboratoire Infrarouge (LIR) and SOFRADIR technology is given.
