摘要
伽氏无焦系统的筒长与视场之间存在反比律关系。本文提出一种以多元法和倍乘法为理论基础的筒长扩展技术,以满足广角条件下获得适用的筒长,并阐述抑制畸变和保证一定出瞳距对物镜与负目镜的结构限约,及其象差的平衡方式。
The tube-length is inversely proportional to viewing field-angle Galilean non-Pow-er. This paper presents the tube-length extended technic basing theory of muti-lens andmultiply, in order to satisfy wide-angle condition to attain serviceable tube-length.And states constracting restriction of objective and negative ocular, when constraintsdistortion and pledge to some interpupillary distance, as well as the systematic aberra-tion balancing method.
