HgCdTe large staring arrays at SOFRADIR

摘要

The staring array numbers of pixels are larger and larger and offer system solutions in the different IR wavebands. At Sofradir, the HgCdTe (Mercury Cadmium Telluride IMCT)material and process, as well as the hybridization technology, have been taken to an even more advanced level of sophistication to achieve these new high performance staring arrays. A lot of technological improvement have been made regarding uniformity of Focal Plan Arrays (FPA), read-out circuits with new functions like the Analog to Digital Conversion (ADC), and finally the reliability of the whole dewar detector and cooler assembly have been drastically increased during these last years. In mid-wave (MWIR) l280x1024 HgCdTe high performance staring array is presented. Also, development trends for future IR detectors are presented.
