<title>Nonuniformity correction using a flood technique and 1:1 mapping</title>

Although the sparse grid Non-Uniformity Correction (NUC) technique can accurately correct individual emitters on a resistor array, it is not a good solution for all projection applications. Due to busbar robbing, the sparse grid NUC breaks down when a large number of emitters are turned on simultaneously. For this case, a more appropriate NUC data collection method is needed. This method involves measuring the entire resistor array at once with a 1:1 mapping between the projector and NUC sensor. Then busbar effects, measured during the NUC data collection, can be accounted for and corrected. This paper presents details pertaining to the flood NUC technique and results. This NUC system is implemented at the Kinetic Kill Vehicle Hardware In the Loop Simulator (KHILS) at Eglin AFB, Florida.
