| 摘 要： | 凝视红外焦平面成像系统中,经常需要根据目标红外辐射强度来修改探测器积分时
间,当积分时间变化后,红外图像的均匀性明显变差。本文探索了一种利用积分时间校正与目前实用性较好的两点温度定标法相结合的焦平面非均匀性校正方案,它不仅使红外图像的均匀性得到较大幅度提高,而且在修改积分时间的情况下图像均匀性不受影响。

| Abstract: | Based on intensity of IR radiation of object, integration time of detector is usually adjusted in steering focal plane array ( FPA) imaging system. Uniformity of IR image badly slackswhen integration time varies. An app roach of FPA non-uniformity correction combining integration time correction with two-point temperature correction, which can improve uniformity of IR image greatly and make uniformity of IR image immune to integration time, is presented in this paper |

| Keywords: | focal plane array non-uniformity correction temperature correction integration time |
