Abstract
Infrared cameras are susceptible to fixed-pattern noise artifacts. These artifacts are due to numerous sources and typically show up as non-uniformities in an IR image of a uniform scene. Devices for and methods of refining non-uniformity corrections in an infrared (IR) camera are provided that correct for remaining fixed pattern noise.
