Abstract

As far as high performance IR detectors are concerned, cooled 2D arrays are more and more used in both IR medium and long wavebands for many different applications. Although it is easy to get an image with 2D staring arrays in comparison with TDI linear arrays, it is more difficult to answer the full system needs in terms of high performances in very tough environmental conditions. As a matter of fact, performances of large cooled staring arrays are mainly limited by the ability of the system to correct the non-uniformities of the arrays and this ability depends on some keys parameters like linearity, uniformity, and stability of operating temperature. These parameters have to remain constant in function of the change of environmental conditions. In this paper, the main key parameters for staring arrays are reviewed and performances of large new SOFRADIR cooled staring arrays are discussed in MW. Finally third generation key drivers are discussed.
