CCD光电探测系统在各个领域中的应用已日益广泛,目前它多应用于目标与背景有足够对比度和静态目标的探测中。在这些情况下目标信号比较容易提取、探测出来,但对强背景下高速运动的弱目标信号提取,对CCD光电探测系统而言就带来一定困难。
CCD photodetection system has been widely used in various fields. At present, it is widely used in the detection of target with enough background contrast and static target. In these cases, the target signal is relatively easy to extract and detect. However, the weak target signal extraction at high speed under strong background poses some difficulties for the CCD photodetection system.
