摘要
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调制传递函数公式 ,并讨论了这两种采样方法对提高动态成像调制传递函数的不同效果 ,分析比较了它们的特点和工程应用的可能性。
Two formula of modulation and modulation transfer function(MTF) of a line CCD optical- electronic imaging system are deduced by both methods of continuous fine signal sampling and interval fine signal sampling.Itwas pointed out that these two methods were different in improving the imaging quality of space line CCD camera.The characteristics of the two methods were compared.
