In this paper, an image-based alignment error correction method for segmented Fresnel primary mirror is proposed. The method can be independent of the spatial structure of the image, and it is suitable for correcting the alignment errors in different imaging scenes. Our method does not need to add any additional devices to the telescope, which may provide an economical and feasible fine phasing correction scheme for the segmented optical telescope.

基于图像的分段菲涅尔主镜对准误差校正方法



本文提出了一种基于图像的分段菲涅尔主镜对准误差校正方法。该方法可以独立于图像的空间结构,适用于校正不同成像场景下的对准误差。我们的方法不需要在望远镜上添加任何额外的设备,这可以为分段光学望远镜提供一种经济可行的精细相位校正方案。
