Abstract

Nonuniformity correction is a necessary image processing step for achieving background limited performance in staring IR focal plane arrays. In developing successful correction techniques, drift in the array output must be considered in order to ensure that the correction coefficients remain valid over a reasonable length of time. We discuss two generic sources of drift, namely system drift and drift originating within the individual unit cells. The latter source of drift is synonymous with 1/f noise and can be shown to have a direct effect on the spatial noise of the array as a function of time. Examples of these phenomena in two current state-of-the-art MWIR staring arrays are given.
