Luminescent cold shield paneling for infrared camera continuous non-uniformity correction

A method of performing non-uniformity correction (NUC) updates on an infrared (IR) detector comprising:

• integrating a plurality of luminescent diodes, etched into a material layer, into a shield surrounding a focal plane array (FPA) of the IR detector to define a luminescent material;
• calculating a corrections table based on subtracting scene data between consecutive image frames for which a luminescent effect of the plurality of luminescent diodes is activated for one frame and inactive for a subsequent frame;
• applying the corrections table with multiple set points to provide corrections to detector offset and detector gain;
• and
• applying the NUC update results to an IR image.
