Paper Abstract

More and more systems are requested to be more compact keeping constant system performances. One of the best approach is to reduce the pixel pitch of the IR detector while new technology improvements are carried out to improve the detector performance. The last developments at SOFRADIR / France for cooled IR detectors are following these trends. As a matter of fact, HgCdTe (Mercury Cadmium Telluride / MCT) staring arrays for infrared detection do show constant improvements regarding their compactness, by reducing the pixel pitch, and regarding performances. Among the new detectors, the family of 15 μm pixel pitch detectors is offering a mid-TV format (384 x 288), a TV format (640 x 512) and a HD-TV format (1280 x 1024). The latest development concerning the mid-TV format is performed according to very challenging specifications regarding compactness and low power consumption. Thanks to recent improvements, the MCT technology allows to operate detectors at higher temperature (HOT detectors), in order to save power consumption at system level. In parallel, the 15μm pitch permits to reach challenging density and spatial resolution. This Focal Plane Arrays (FPA) is proposed in different tactical dewars, corresponding to various systems solutions.
