| Abstract: | This paper introduces the principle of differential comparing MTF (Modulated Transfer Function) being applied to automatically focus for remote sensing camera and makes the experimental research with white/black grating and photograph from the satellite being used as experimental objests. The results show that this method has the advantages of high repetitive precision, high action sped and wide available range, and What is more, its precision is hardly affected by image displacement vertical to optical axis. Therefore, it is suitable to CCD(Charge-Coupled Device) remote sensing camera. |
