Abstract

This paper describes the results of a long, intensive research and development effort related to the subject of nonuniformity correction (NUC). The study has been performed in order to increase the performances of cooled and uncooled FLIR's. The causes of NUC instability have been investigated in parallel with a general approach used for a very high dynamic range, and for very low noise FLIR performances. The results of this research have been implemented on a special design, enhanced vision system (EVS), camera for lending applications, and on ucooled camera FLIR's. This paper contains measured data on optics temperature influence on FLIR performance and theoretical models to explain the measured data.
