【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。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,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保证图像均匀性不受影响。更多还原

【Abstract】 In staring focal plane array imaging system, integration time of detector is often adjusted according toobject’s intensity of IR radiation. Uniformity of IR image gets worse when integration time varies. A new method ofFPA non-uniformity correction, combined integration time correction with two-point temperature correction, whichcan greatly improve uniformity of IR image and make uniformity of IR image immune to integration time, is presented.更多还原
