Abstract
The paper describes structure and principle of TDI-CCD image sensor. With help of the Modulated Transfer Function (MTF), the negative effect on image quality is fully analyzed, which is caused by the mismatch between TDI-CCD line scanning and velocity of image motion. After theory analysis and experiments, the results show that within the Nyquist frequency, only the synchronous error is strictly controlled in the range of ±2%, and a continuous four-phase imaging clock is employed, the effects of image motion is basically eliminated during process of imaging.
