Study on Infrared FPA Nonuniformity Correction

Infrared nonuniformity has limited the quality of staring infrared focal plane array (FPA) image. In this paper, we give a definition of infrared nonuniformity and analyze the source of nonuniformity in detail in order to get a clear concept on this subject. Several correction algorithms and their experiment results are also presented.At the end of the paper,a brief summary is made on the characteristics and applications of these algorithms. [WT5”HZ〗
