As far as high performance IR detector are concerned, MWIR cooled 2D arrays are more and more used for high quality systems which need the uniformity and quality of the response in order to offer a good non uniformity corrections (NUC) and a stable IR detector calibrations. The aim of this paper is to demonstrate the state of the art of Sofradir's detectors regarding the NUC. We will start by presenting all the present performances (Residual Fixed Pattern Noise, two or three points corrections, linearity, stability of the correction versus the time and versus ageing, stability with the focal plane temperature, fast cool down applications, etc.). We will then make a comparison with other 2d arrays' performances, using the same methods of calculation as presented in the datasheet. Finally, we will present a perspective about the advanced studies carried on at Sofradir to increase the performances in this critical area in terms of technological progress or calculation method. |
