【Abstract】 The nonuniformity of infrared focal plane array(IRFPA) and its influences on infared systems are introduced. The limitations of current calibration nonuniformity correction(NUC) algorithms and some problems of a popular adaptive NUC method are analyzed. The practicability, limitations and some available improvements are investigated.更多还原
