摘　　要：液体透镜相对固体透镜最大的优点是无需使用伺服电机等大型驱动装置，便可实现变焦。通过对国内外液体变焦技术的研究进行总结，依据不同的变焦机理对液体透镜进行分类，把液体变焦形式分为变曲率半径型和变内部液体型。变曲率半径型液体透镜的驱动原理繁多，分别进行详细介绍。主要从变焦机理，设计结构，透镜的成像优缺点等方面分析。最后，基于液体透镜研究现状，提出一种新型变焦液体透镜结构来改善温度场对液体透镜性能的影响。
The advantage of variable focus liquid lenses over solid lens systems is their tunability without the use of large actuators such as servo motors. It reviews and summarizes the domestic and the foreign scientific achievements on the varifocal-liquid techniques. Variable focus liquid lenses can be categorized as tuned by the curvature radius of the lens or the liquid in use according to the concept of tunability. Depending on the driving principle of different types,variable radius of curvature of liquid lenses are introduced in details, by introducing the design of the structure, analyze advantages and disadvantages of liquid lens. Finally, for the development status of liquid lenses, it points out a new structure for the investigation of variable focus liquid lenses techniques to eliminate the effects of temperature field.
