摘要

一种在物镜系统中具有稳定反射镜的光学观察装置，其排列使得图像在垂直于该装置视线的轴上不受振动的稳定条件为2 2s 1 1 - + = r fr m，其中r为耦合比;S为反射镜与位于反射面前的部分物镜系统沿光轴的距离;F为物镜系统中位于反射面前面的部分的焦距;m是设备完整光学系统的总放大倍率。

The Domino Inequalities for the Symmetric Traveling Salesman Problem

An optical viewing device having a stabilized mirror in the objective lens system, the arrangement being such that the conditions for stabilization of the image against vibration about an axis perpendicular to the line of sight of the device is 2 2s 1 1 - + = r fr m WHERE R IS A COUPLING RATIO; S IS THE DISTANCE ALONG THE OPTICAL AXIS BETWEEN THE MIRROR AND A PART OF THE OBJECTIVE LENS SYSTEM THAT LIES IN FRONT OF THE REFLECTING SURFACE; F IS THE FOCAL LENGTH OF THAT PART OF THE OBJECTIVE LENS SYSTEM THAT LIES IN FRONT OF THE REPLECTING SURFACE; AND M IS THE OVERALL MAGNIFICATION OF THE COMPLETE OPTICAL SYSTEM OF THE DEVICE.
