The relation between response output and radiate input of the detectors of the IRFPA is nonlinearity in big dynamical range.Due to the result of the experiment,we knew that the response curve of the detector obeys S-curve model.However,the traditional S-curve model correction needs great deal of calculate.And the parameters drift as time goes by.The parameters need to be compensated which may affect the continuous working of the infrared detectors and at the same time makes the system complex.New method combined with two-point NUC correction,which reduced calculate a lot.Based on least mean square (LMS) algorithm,the parameters of the S-curve model is compensated to solve the problem of the traditional method in this paper.And the new improved algorithm is realized.Its efficiency and superiority are clarified by experiment.The algorithm has better engineering practice significance.
