Paper Title:
Effect of Image Motion and Vibration on Image Quality of TDICCD Camera
  Abstract

Image motion and vibration are significant factors influencing image quality of satellite-based TDI camera. In order to learn their effect on TDICCD, motion degradation models at two directions were established. Based on the models, Line spread functions (LSF) for image motion of different types and strict expressions of MTF for abnormal linear image motion were deduced. Modulation transfer function (MTF) for sinusoidal image vibration was calculated through numerical integration. Geometric distortion was evaluated by linear part of phase transfer function (PTF). The results indicate that abnormal linear motion and high frequency vibration cause space-invariant image blur while low frequency vibration brings space-variant image blur and geometric distortion.
