激光反导系统中的电视瞄准镜

TV sight lens in an antimissile system

长焦变焦镜头用于军事瞄准时，变焦过程中较大的光中心漂移，降低瞄准精度。阐述了在长焦变焦镜头的设计、研制中，所采用的特殊设计和生产工艺，它们较好地解决了光中心漂移、小型化设计、自动控制等问题。

When zoom lens are used for military sighting,the drift of optical center caused by the change of focus length will reduce the sighting accuracy severely.In order to solve the problem,we employed two sets of compensation lenses,called conjugation lens sets,to eliminate the image plane shift. Also this paper discussed the miniaturization design,manufacture technology and automatic control of the system.
