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。 Staring infrared focal plane imaging system often need to modify the detector integration time according to the target infrared radiation intensity, when the integration time changes, the infrared image uniformity is significantly worse. This paper explores a focal plane nonuniformity correction scheme which integrates the integral time correction and the current practical two point temperature calibration method, which not only greatly improves the uniformity of the infrared image, but also improves the integration time In the case of ensuring image uniformity is not affected.
