Correction of photoresponse nonuniformity in IR staring sensors is investigated. Spatial noise expressions for uncorrected, one-point corrected, and two-point corrected imaging are developed. These theoretical results take into account the properties of the IR source, sensor constants, and spatial variations in the IR imaging device. To demonstrate the application of these results, both theoretical and actual spatial noise curves for a platinum silicide IR sensor are presented.
