为了深入地研究平面镜系的成象原理,需象共轴系统一样,抽象出其原理结构来。由数个平面镜以一定的方式固接在一起,称为平面镜系。反射棱镜由反射部分与折射部
In order to study the imaging principle of the plane mirror system in depth, it needs to abstract its principle structure like the coaxial system. By a number of plane mirror fixed together in a certain way, known as the plane mirror system. The reflecting prism consists of a reflecting part and a refracting part
