| 中文摘要: |
| 介绍了转动架驱动头盔面窗进行多个光学性能参数测量时 ,能使固定的测量光束在透射头盔面窗上的任何点通过其两个焦点 ,实现正确的测量。关键在于这种双焦点曲面的几何特性和转动架的独特设计 |
| 英文摘要: |
| This paper describes a rotational stand,which can drive a helmet viewing window rotating to appointed any place for measuring several optical parameters,and let a fixed measuring beam pases through both of focuses when it passes though anywhere on camber.Thus is performs a correct measurement.What counts is the geometric character of the camber and unique design of the rotational stand. |
