Abstract

Staring infrared (IR) detector arrays will have many applications in both imaging and nonimaging systems if the required signal conditioning can be performed in a simple low cost manner. Due to the large numbers of detectors and the high data rates inherent in staring IR arrays, the normal digital signal processing approach to the data handling problem is not desirable. One potential alternative to the all-digital approach is an electro-optical technique that uses both parallel optical processing as well as analog and digital processing. This hybrid technique offers both simplification and lower cost advantages over present techniques, as well as potential improvements in performance. This paper discusses these electro-optical techniques and their system advantages.
