Abstract
A luminescent diode surface within the cold shield of an infrared camera to allow for continuous non-uniformity correction with uniform irradiance across an infrared IR detector array. Further provided by the inclusion of a luminescent diode surface within the cold shield paneling is the ability to change the diode bias providing a negative luminescent effect while utilizing reverse bias and an electro-luminescent effect while utilizing a forward bias. This may then further allow for multiple set points to provide continuous offset and gain correction and to correct non-linear response effects.
