潜望镜连续变焦光学系统设计
|
摘要
基于潜望镜的基本原理,设计了一种焦距252 mm~504 mm的连续变焦潜望镜光学系统,该系统将传统的采用翻转变倍方体的跃式变倍方式改为沿轴向移动变倍镜组和补偿镜组实现连续变焦的方式。系统经仿真验证及像质分析证明,各项性能指标均满足设计要求。测试结果表明,光学系统空间分辨率小于2′。
A continuous zoom optical system with working focal length of 252 mm~504 mm was designed based on the basic principle of periscope.Instead of traditional flip zooming which is a discontinuous zoom mode,the system adopts the mechanical-compensated optical configuration in which the given variable lenses groups move along the optical axis driven by a cam to achieve the continuous change of effective focal length(EFL).Through simulating and imaging quality analysis,it is proved that all the performance indicators meet the design requirements.Test results show that spatial resolving ability of the optical system is below 2′.
