Study of non-uniformity in infrared focal plane arrays

The non-uniformity correction of infrared focal plane arrays is the essential part in the stare type infrared system.The article analyses the formation mechanism of non-uniformity from the angle of optical imaging principle.According to the limitation of traditional neural network algorithm,it makes improvement from ideal expectation output,error function and iterate step.The improved algorithm is verified by the simulation experiment and the result shows that the new algorithm has obvious advantage in correction effect.
