有限远目标潜望镜光学系统设计

Optical System Design of Periscope for Finite Distance Target

基于潜望镜的基本原理,设计了一种用于教学训练的对有限远目标成像的潜望镜,该潜望镜是将投影仪投射出的有限远的模拟目标经物镜前组准直成平行光,再分别经物镜后组与转向透镜前组组成的望远系统、转向透镜后组与目镜组组成的望远系统传递到人眼,实现单双目变换、准双目观察、光学测距等功能。该系统视场光阑与孔径光阑重合并设置于转向透镜组之间的平行光路中。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。

Based on the basic principle of the periscope,the optical system of the periscope imaging to the finite target is designed for teaching and training.The optical system consists of objective lens group,the steering lens group and the eyepiece group.The simulated target from the projector with finite distance is collimated by the former group of objective lens.Then passes the telescope consisting of the back group of objective lens and the former group of the steering group,the telescope consisting of the back group of the steering group and eyepiece group and transmits into eyes.It realizes the functions of the single binocular transformation,quasi binocular observation and optical ranging.The field diaphragm is located in the parallel light path of the steering lens group,the position of which coincides with the position of the apertures diaphragm.The simulation results and the analysis of the image quality demonstrate that each performance index meet the design requirements.
