| Abstract: | The principle of push-broom TDI-CCD imaging camera and the characteristics of TDI-CCD imaging are discussed in this paper. Some factors affecting modulation transfer function of TDI-CCD camera system which include pixel pitch, charge transfer efficiency, velocity mismatch and charges discrete moving are presented. And the MTF of discrete system for one-dimensional static case is calculated as well. At last, the relationships between TDI stage and synchronization, signal-to-noise ratio, dynamic range are derived. |
