Modulation transfer function in push-broom camera limits resulting from mechanical vibration

It is important to analyze the degradation of the image quality caused by camera vibration in order to determine the tolerance of the stabilization in the satellite attitude.We have proposed an improved model for calculating the modulation transfer function (MTF) of a push-broom CCD camera,and constructed two kinds of experiment system to measure the degradation of the MTF caused by vibration.The calculated MTF with respect to low-frequency and high-frequency vibration agree with the experiment results,indicating the model is valid for studying the stabilization of satellite attitude.
