This is the view through a telescope demonstrating the optical effect known as Newton's Rings, whereby reflected light rays interfere with one another and produce a pattern.
这是利用望远镜展示名为“牛顿圈”的光学效应，折射光线彼此干涉，形成了这些条纹。
Spherical Aberration — causes light rays passing through a lens (or reflected from a mirror) at different distances from the optical center to come to focus at different points on the axis.
球差-使以不同孔径角穿过透镜(或从镜面上发射)的光线不能聚焦在轴上的同一点。
