AI Technical Summary
During satellite jitter and orbital changes, the image quality of the space-based full-disk solar polar-orbiting telescope deteriorates due to image shift and changes in spot size. Existing image processing methods are ineffective and cannot maintain image stabilization during long-distance orbital changes.
An image stabilization system is employed, comprising an incident unit, an image stabilization mirror unit, an image stabilization zoom mirror unit, a detector, and a numerical control unit. By adjusting the angle and focal length of sunlight, combined with a polarization analyzer and multiple mirror groups, spot compensation and focal length adjustment are achieved to ensure a constant solar image size.
Maintaining the stability and clarity of the solar image during satellite jitter and orbital changes improves imaging quality, overcomes the image stabilization bottleneck during long-distance orbital changes, and achieves high-resolution imaging.
