摘　　要：随着车载光电系统的发展,多功能合一的观察瞄准镜成为发展趋势。将电视观瞄/可见光直视观瞄系统进行共光路设计,可见光直视观瞄系统放大倍率为8×、视场为5°、出瞳直径为φ4mm、出瞳距离不小于15mm;电视观瞄系统F数为6、焦距为110mm。同时,对设计结果进行公差分析,根据公差分析结果制定严格的零部件加工公差及系统装调方案,系统结构紧凑,成像良好,对2.3m×2.3m的目标进行观瞄,识别距离大于4km,满足指标要求。With development of vehicle-borne opto-electronic system,the sight with multi-func- tions has become a trend. This paper presents common path design for TV sight/visual sight. For visual direct-view sight, magnification, field of view, exit pupil diameter and eye relief are 8^×, 5°, φ4 mm and not less than 15 mm respectively, while F number and focal length are 6 and 110 mm respectively for TV sight. Then tolerence of the results is analyzed. Finally, strict tolerance of parts fabrication and system assembly are formulated according to the analysis of tolerance. For 2.3 m× 2.3 m target, identification distance is more than 4 kin, which can meet imaging demands.
