Based on the analysis of the existing problems of ordinary nonuniformity correction algorithms for IRFPA,a method of two-point correction for IRFPA with nonlinear response is proposed.The algorithm is curve fitting based on least square approximation.Compared with the traditional two-points correction and four-points correction,this method has perfect performance of high precision,broad dynamic range and easy to realize in engineering.
