摘要
在对飞行目标的实际情况监视和记录时,实况记录系统是一种非常重要的电视设备。变焦距望远镜是其重要的组成部分,介绍了变焦距镜头对像面补偿时常用的机械补偿和光学补偿的优缺点。并根据某实况记录项目的指标要求,详细地论述了光学系统的方案确定,主光学系统和凸轮变焦距系统的结构设计。对完成的实况记录系统进行了检测,其光学系统的目视鉴别率达到了53l p/mm,不仅各项技术指标达到要求,对其他同类型变焦距镜头的设计具有一定的借鉴作用。
In realtime monitoring and recording of flying objects, live recording system is significant TV equipment. Zoom telescope is one of the essential components. In this thesis the author introduces the advantages and disadvan tages of mechanical compensation and optical compensation frequently used in zoom lens image compensating. And according to the specification requirements of a certain live recording project, the author thoroughly discusses the de sign scheme confirmation of the optical system as well as the structural design of the host optical system and cam zoom system. The finished live recording system was tested, and test result shows that the visual identification rate of the optical system reaches 53lp/ram and the system meets all the required technical specifications. The design scheme can be used for a reference in the design of zoom lens of other same types.
