摘　　要：首先推导出红外焦平面阵列非均匀性的线性校正方法,之后提出了三种硬件实施方案,分析了其在工程实施的特点和结果上的区别,并讨论了模拟校正、高次函数校正问题以及盲元补偿的实施方法。数字算法可用FPGA予以实现,校正的最后极限来自红外焦平面阵列响应的不稳定性。Three projects for nonuniformity correction of infrared focal plane are proposed after the deducing of the linear correction algorithm.The characteristics of their applying to engineering and the resultant differences are analyzed.The analog NUC scheme,polymomial algorithm and compensation of blind pixels are discussed also.All the digital projects here were integrated into FPGA successfully,and the final results is limited to the response instability of IRFPA.
