Enhanced Performance IR Focal Plane Arrays Using Adaptive Subtraction

Abstract

This memorandum describes a compact, adaptive circuit, realisable at the pixel level of Infrared focal plane detector arrays. The technique removes unwanted currents from the array, permitting more signal current to be integrated at the pixel. This can be used to improve performance, improve uniformity of signals from the array and simplify associated electronics. The choice of advantage conferred by this scheme depends on the system in which it is employed. Great Britain.
