摘要 基于液体透镜的光学变焦系统无需机械运动即可达到变焦的目的,因此近几年来在光学应用中备受关注。在双液体透镜的基础上,设计了一种导电层连通的三液体自变焦补偿透镜,该液体透镜采用圆柱形结构,可通过控制电压来改变透镜中两个液体界面的曲率半径,以达到自变焦补偿功能。对该液体透镜的结构进行了详细分析,并求得该液体透镜的最小化结构表达式。依据高斯理论探讨了透镜相关参数对新型液体透镜变倍比及视场角的影响。 Optical zoom system based on liquid lens is used in many optical fields in recent years because it can achieve zooming without mechanical movement.A new lens with three layers of liquids and connected conducting layer is proposed.This liquid lens is cylindrical and it can zoom and compensate by itself by changing the voltages applied to control the radium of liquid interfaces.The structure of the liquid lens is analyzed in detail,and the minimum structure expression of the liquid lens is obtained.On the basis of the Gaussian optics theory,the effects of lens parameters on zooming performance including zoom ratio and field angle of the system are studied.
