Paper Abstract

In traditional designs of a NUC (non-uniformity correction) system, a rotating chopper-wheel (or a blurring/deform lens) is used to separate the outside scene and the inside FPN (fixed pattern noise) on the FPA (focal plane array). To design a NUC system removing the chopper-wheel (chopper-free) and its control electronics and hardware will not only considerably reduce the cost, but also require less space to fit the NUC system. In this paper, we describe a recently developed CF (chopper-free) NUC system. This system is simpler to build, costs less, and requires less space, as compared with traditional designs.
