4034 Vibration Compensation Method for Flexible Optics Using Image Information
Details
Today, space telescopes with flexible structure have been proposed and some of them are ready to be demonstrated in orbit. A serious problem in the imaging system with such a telescope is its bending vibration, inevitably caused by satellite attitude control. This paper proposes a method to compensate vibration of the satellite overall, using only images taken by the telescope. To extend the dynamic range of sensing vibration, the state estimator we propose uses not only image shift information from successive images, but also motion blur information from each image.
