参考文献[1,2]将反射式望远镜入射光瞳中心部分的屏蔽看作是改变远距离发光点衍射图像中能量分布特性的一个因素。在一些理论研究工作的基础上,建议屏蔽部分最好不要超过入射光瞳面积的10～12%,这相当于有一个大小为(0.3～0.35)D 的圆屏蔽物掩盖着直径为D 的入射光瞳。同时,参考文献[3,4]列出的结果说明,当有效孔径的中心部分被大小为(0.6～0.8)D 的屏蔽物掩盖时,随
References [1, 2] consider the shielding of the central part of the entrance pupil of a reflective telescope as a factor that changes the energy distribution characteristics in the diffracted images at long-distance glow points. On the basis of some theoretical work, it is suggested that the shielding part should not exceed 10-12% of the incident pupil area, which is equivalent to having a circular shield of size (0.3-0.35) D to cover the incident of diameter D Pupil In the meantime, the results listed in Ref. [3, 4] show that when the central part of the effective aperture is covered by a shield of size (0.6-0.8) D,
