摘要
文章从理论上推导了线阵CCD相机间歇细分采样和连续细分采样成像所得到的光电图像调制度和MTF公式,并讨论了这两种采样方法对提高动态成像MTF的不同效果,分析比较了它们的特点和工程应用的可能性。
In this papers two fomula of modulation and MTF of a line CCD optical electronic system are deduced by toth methods of contiuous fine signal sampling and interval fine signal sampling. It was pointed out that these two methods were different in improving the imaging quality of space line CCD camera. At end of the paper, characteristics of the two methods were compared.
