Abstract

The post correction uniformity performance of infrared 2D starring arrays is a key factor to ensure the best IR image quality at the camera level. SOFRADIR has conducted several studies to improve both the post correction uniformity performance and the correction tables stability over the time periods, the readout integrated circuit configuration and the environmental conditions. Indeed, works have been performed on the homogeneity technology deposits, on the improvement of the readout circuit linearity and on the optimization of the dewar design to reduce the parasitical fluxes. Thanks to these improvements, Sofradir offers to its customers high level post correction uniformity performances as well as excellent correction tables stability for the mid wave and long wave infrared band. Thus, the calibrations constraints are reduced at the camera level and the image quality is optimized over a large camera utilization conditions.
