一、像差的概念一束平行光线经过理想的光学系统后聚集于一点。对于无屈光异常的眼球 ,只有通过瞳孔中心的光线才满足这一条件 ,其它光线特别是由瞳孔周边进入眼内的光线经过不对称和不规则的屈光介质 ,发生方向偏差 ,光线在视网膜平面放大 ,从而产生像差 ,包括球面像差 ,斜射? First, the concept of aberration A bundle of parallel rays through the ideal optical system gathered in a little. For non-refractive eyeball abnormalities, only the light through the center of the pupil to meet this condition, other light, especially by the pupil into the eye around the light through the asymmetric and irregular refractive media, the direction of deviation, the light in the retina Plane enlargement, resulting in aberrations, including spherical aberration, oblique?
