| 摘 要： | 介绍一种用两组元透镜来实现倒象和连续变倍的双筒望远镜设计。该设计在物镜焦面位置安装带刻线的分划板 ,可对目标进行瞄准和测量。特别是在系统不另设可变光栏的情况下 ,利用光学系统透镜边框作孔径光栏 ,使系统在整个变倍过程中不仅出瞳直径和出瞳距离均变化不大 ,而且系统与定倍望远镜一样具有较大的象方视场、出瞳直径和出瞳距离 ,从而使系统无论昼夜使用都具有真正的变倍作用和良好的观察效果。

| Abstract: | The design of a binocular telescope with two group- element lense to achieve inverted image and continuous variable power is described in the paper.The reticle is located at the focal plane of the objective,the pointing and measurement for the targetcan be carried out with it.When no variable diaphragm is equipped in the system and the side- frame of lens is used as an aperture diaphragm,not only the variations of both the exit pupil diameter and the exit pupil distance are not large during the full varying power process,but the system also has a larger apparent field,exitpupil diameter and exit pupil distance as well as the fixed power telescope,thus the system can provide a true varying power ability and a good observation effect no matter day or night. |
