广角伽氏无焦系统的筒长扩展技术
The Tube-Length Extended Technic For Wide-angle Galilean Non-Power System
-
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。Abstract: The tube-length is inversely proportional to viewing field-angle Galilean non-Power.This paper presents the tube-length extended technic basing theory of muti-lens and multiply,in order to satisfy wide-angle condition to attain serviceable tube-length.And states constracting restriction of objective and negative ocular,when constraints distortion and pledge to some interpupillary distance,as well as the systematic aberration balancing method.
