摘要
本文系统的分析和论证了变焦距系统像点漂移产生的原因;比较了不同结构形式和倍率选段的变焦距系统对像点漂移量的影响,为跟踪测量变焦距系统设计初步选型提供了客观依据;给出一种具有实际意义的校正变焦距系统像点漂移的有效方法;提出了以像点漂移允差为依据制定变焦距系统光学元件中心偏差公差的方法和制定机械结构一些相关公差的参考依据。
In this paper,it's analysed and expounded the reason of the tra- nsverse image displacement in zoom system systematically,contrast- ed the effect on transverse image displacement of different contruc- tion type and multiplying power of different cam-curve selection in zoom,system,provided the objective basis to track and surrey the premilinary type selection in zoom system design,put forward a eff- ective method to rectify the transverse image displacement in zoom system applying in practical engineering,and produced a way to ma- ke the center error tolerance of component according to the transve- rse image displacement tolerance.
