摘要：
For the limitation of the application of classical scene correction algorithm in infrared Focal Plane Array (FPA) at present, decomposition of non-uniformity characters correction algorithm was studied. We analyze the factors that construct the non-uniformity of the FPA and decompose the non-uniformity of FPA into blind point, row/column non-uniformity, gradients non-uniformity. etc by character, apply different processing algorithms to different kinds of non-uniformity. We experiment this algorithm on self-developed infrared equipment. The result indicates that this algorithm is of high accuracy as well as good application, and can solve the degeneration phenomenon such as 'ghosting' in classical scene correction.
