For the difference of infrared focal plane array(IRFPA) materials, manufacturing process, and multi-channel circuit design, every pixel on the IRFPA has different responses under surface blackbody, thus the output is not uniform. The non-uniformity of infrared detector pixels(non-uniformity) affects the quality of target radiation detection. The characteristic of the infrared target cannot be determined due to infrared focal plane non-uniformity. In this study, the blind element is detected and compensation...
