| 摘 要： | 当潜望式光学系统中反射镜绕机械轴转动时，影像会在视场中绕光轴旋转严重影响观瞄。消像旋棱镜可以使像产生反向转动从而消除这种影响。从探索潜望式瞄准镜中消像旋棱镜的装调工艺出发，通过对2种常用消像旋棱镜在光学系统中对光线折转的分析，提出了其光机装调过程的判断依据，总结了2种消像旋棱镜应用的装调工艺方法，并提出了在平行光路中检测消像旋棱镜固定前后的分辨率以保证成像质量。经过多个项目的验证，此方法能有效降低消像旋棱镜的装调难度，装调后消像旋棱镜光轴与系统基准轴偏差控制在30以内。

| Abstract: | When the reflection optical system of periscope mirror rotates around mechanical shaft, the reflected image in the view field rotates around the optical axis which greatly affects observation. Offsetting image rotation prisms can eliminate the influence by spinning in the opposite direction. Though the analysis of two widely used offsetting image rotation systems, the criterion of the assembly process is raised, two typical methods for offsetting image rotation prisms are concluded, and the detection of offsetting image rotation prism fixed before and after the resolution in parallel light is put forward to ensure the imaging quality. The method is proved to be effective in reducing the difficulties in alignment of offsetting image rotation prism system and improving image quality. The windage between the optical axis of the offsetting image rotation prisms and system norm axis can be controlled less than 30″. |
