针对目前非均匀性校正方法存在的问题与不足,介绍了适于红外焦平面阵列探测器的非均匀性校正处理方法。其特点是用一个触发电路使基于场景的非均匀性校正电路对探测器的运动信号做出响应。实验结果表明,在没有劣化静态场景的情况下,该方法实现了运动场景信号的校正,不仅消除了红外焦平面阵列响应的非均匀性,而且补偿了其漂移。 In view of the existing problems and deficiencies of nonuniformity correction methods, a nonuniformity correction method suitable for infrared focal plane array detectors is introduced. It is characterized by a triggering circuit that enables the scene-based non-uniformity correction circuit to respond to the detector’s motion signal. The experimental results show that this method can correct the motion scene signal without deteriorating the static scene, which not only eliminates the nonuniformity of IRFPA response but also compensates its drift.
