Paper Abstract

Pixel-to-pixel radiance nonuniformity is the prominent noise source from resistive arrays and must be compensated or otherwise mitigated for high-fidelity testing of infrared imaging sensors. Many of the current advances in the capability of resistive array, IR scene projection rest in the improvement of nonuniformity correction (NUC) schemes. Early NUC schemes address the problem of optical crosstalk or spreading and the types of algorithms available that help to mitigate its effect when individual pixel radiometry is performed. However, there has been relatively little work done on scene-based correction to date where the effects such as power drops across the emitter array and thermal crosstalk are important to consider. This paper will examine potential problem areas in scene-based correction and discuss possible algorithms that could be used in a scene- based NUC approach.
