Stable imaging of space optical camera with high resolution and large field of view

摘要

Aiming at the problem of the inconsistency of the point spread function of each field of view of the high-resolution large-field space optical camera and the reduction of the imaging resolution caused by the influence of atmospheric interference during orbit imaging. Both the optical system design and image restoration are used to reduce the inconsistency of the point spread function of each field of view of a high-resolution large-field space optical camera. By dynamically predicting the change of the point spread function of the optical system, the impact of atmospheric interference on the spatial resolution is reduced. The experimental results show that the method used in this paper can effectively improve the imaging stability of high-resolution large-field spatial optical cameras.
