Abstract

To utilize the full performance advantages of staring infrared imaging systems currently under development, it is necessary to compensate for the characteristic fixed pattern "noise" which is present at the output from these IR focal planes. Since many of the applications for staring sensor systems require low power dissipiation configurations, it is necessary to develop automatic non-uniformity compensation electronics which have much lower power dissipation requirements than conventional digital compensation techniques. This paper discusses the sources of the non-uniformities and describes the typical characteristics of elevated temperature staring arrays. An analysis is given which shows how detector/CCD electrical coupling techniques strongly influence the compensation implementation and finally a review of circuit configurations for the compensation function will be given which show that very low power dissipation circuitry can be developed which meet the performance power dissipation requirements.
