中文摘要：

液体透镜是一种新的光学元件,它实现了无机械变焦,给变焦系统的设计提出了一种新的概念。使用一种比较少见的口径较大的液体透镜组成变焦系统。对液体透镜的原理进行了介绍,对液体透镜变焦系统的设计方法进行可行性分析,给出了各种设计方案,使用Zemax对变焦系统进行仿真。针对大视场给出使用了前置透镜组的方案,得到了一个视场60°,变倍比6.2倍的变焦系统。

英文摘要：

Liquid lens is a new optical element,which implements zooming without mechanical moving.A new way to design zoom lens system was proposed.A rare kind of liquid lens with large aperture was used to design a zoom system.The principle of the liquid lens was introduced first,then the possibility of designing the zoom liquid lens system was analyzed and various design plans were provided,and finally the Zemax software was utilized to simulate zoom system.A frontal lens group scheme was given aiming at the large field of view（FOV）,and a zoom system was achieved with the FOV of 60°and the zoom ratio of 6.2.
