IET Control Theory &Applications, Volume 15, Issue 15, Page 1931-1941, October 2021., 2021 Abstract Scanning imaging can be used to obtain wide field‐of‐view, high‐resolution remote‐sensing images with a telescope lens. However, the motion between the image and the sensor causes blurring during scanning, which reduces the image quality.
