Abstract

Advances in IR Focal Plane Technology now make two dimensional detector arrays possible. It is expected that with two dimensional detector arrays the performance of IR Sensors will improve significantly. Ideally, the sensitivity improvements should scale with the square root of the number of detectors in the array. However, with larger IR arrays interdetector variations need to be compensated for. In this paper we consider quantitatively the sensitivity limitations effected by interdetector variations in quantum efficiency and spectral response, and with noise associated with calibration. Correction for the interdetector spectral variations are the most difficult and are the prime cause for sensitivity limitations. The limited sensitivity manifests itself, in scanning arrays as spectral streaking.
