| Abstract: | This paper is aiming at analysis of the MTF degradation mechanism caused by the assembly precision of TDICCD camera.Specifically,by considering the satellite attitude image shift mechanism introduced by the assembly precision,the influence on modulation transfer function(MTF) is detailed discussed.The results show that the analysis can provide a basis for setting reasonable specification of assembly precision of TDICCD camera. |
