摘要	Among numerous nonuniformity correction (NUC) algorithms, two-point calibration-based NUC is the most effective and commonly-used one for scientific and commercial infrared imagers. However, conventional two-point NUC requires two references at different level of flux, which is sometimes difficult to achieve in field applications. To overcome the restriction, a single-reference-based solution for two-point nonuniformity correction of infrared focal plane arrays is proposed in this paper. A single reference, which is easy to obtain, and a spherical reflecting warm shield are required to conduct this NUC method. The design method of this warm shield is developed. Several NUC experiments were performed to validate the proposed method. The experimental results indicate that the proposed NUC method yields almost equivalent performance with the conventional two-point NUC method, moreover it is economical and convenient in practical applications.
