Abstract

HgCdTe (Mercury Cadmium Telluride / MCT) staring arrays for infrared detection do show constant improvements regarding their compactness and performances. New detectors are now proposed offering system solutions in the different IR wavebands and profiting of the latest technology improvements as well as MCT performance advantages and cost reduction. Among these new detectors, one can find the family of 15 µm pixel pitch detectors including a mid-TV format (384 x 288), a TV format (640 x 512) and a twice-TV format (1280 x 1024). The latest development concerning the mid-TV format is performed according to very challenging specifications regarding small cost and low power consumption. These Focal Plane Arrays (FPA) are integrated in dedicated tactical Dewars, taking advantages on last development in coolers manufacturing and Dewar assembly. Another development axis at CEA\LETI-LIR and Sofradir concerns the avalanche photodiodes for FPA sensitivity improvement. This very promising technology is dedicated for low flux applications as active imagery, hyperspectral applications or small aperture systems. New development results are presented and future trends are discussed.
