A preprocessor architecture to equalize focal-plane detector-array elements

Requirements always exist to improve and extend the uniformity and linearity of detector (or any sensor) responses in order to improve performance of a device of a system, or to increase the yield and lower the cost of "acceptably good" sensors or arrays of sensors. In this paper, the mechanization of a concept which was proposed by Sawchuk [1] is examined, one which uses array data directly to construct a distribution function of the input from each sensor, and which compares that function with a stored reference function in order to generate a correction map.
