| Abstract: | 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. |
