中文摘要：

分析了电润湿液体变焦透镜的光学特性和变焦系统设计理论,将各组元焦距作为变量,列出了该液体透镜变焦系统的变焦方程.利用粒子群算法优化求解变焦方程,得到符合条件的初始结构;再利用优化设计软件进行像差平衡,设计了一个具有4片液体透镜,焦距为20～120mm的大变倍比液体透镜变焦系统.系统各焦距处光学传递函数在66lp/mm处均大于0.3,畸变小于2%,满足设计要求.

英文摘要：

The optical properties of the electro-wetting liquid zoom lens and the theory of zoom lens design were analyzed.Make the focal length of each element be variable and list the equations of the liquid lens zoom system.An initial liquid zoom lens structure by utilizing PSO and balance aberrations was studied by using optical design software.A 6×（20～120mm）zoom ratio liquid lens zoom system with four pieces of liquid lens was designed.The MTF at 66lp/mm of this system at each focal length are greater than0.3,and distortion is less than 2%,which meets the design requirements.
