Atmospheric turbulence and telescope aberrations all contribute to image degradation with ground-based telescopes.
相位差法利用在焦面和离焦面上同时采集到的短曝光图像,恢复出瞬时波前相位分布,然后根据大气湍流的统计特性进行平均,可以实现对望远镜像差的估计。

It used to apply only to reflecting telescopes in which the primary mirror was a paraboloid, and thus capable of forming an image all by itself.
它过去只用在抛物面反射望远镜上，这种镜子只用主反射镜就能成像。
