摘要: 介绍一种非移动式变焦技术液体变焦技术。对国内外液体变焦技术的科研成果进行了归纳和总结,介绍了液体变焦透镜的基本原理及实现形式,分析了液体透镜的优异性能及其对光学领域的影响。根据液体变焦技术的发展现状和工程应用情况,指出液体变焦技术目前的研究重点主要应放在如何克服温度场和重力场对液体透镜性能的影响等机理研究,液体透镜的离轴系统和非对称系统的设计以及加速液体透镜的产品化等工作上。Abstract: This paper introduces a new zoom lens technique that is varifocal-liquid technique. First of all, it reviews and summarizes the domestic and foreign scientific achievements on the varifocal-liquid techniques, and gives the basic principle, realization forms and the classification of liquid lenses. Then, the paper evaluates the excellent performance of the liquid lenses and their influences on optical fields, especially the revolutionary change brought by varifocal-liquid technique. Finally, for the development status and application engineering situation, it analyzes the urgency problems unsolved in varifocal-liquid technique. Finally, and it points out that the investigation and development of varifocal-liquid techniques should focus on the mechanism research to eliminate the effects of temperature field and gravity field on the performance of liquid lenses, the design of off-axis system and asymmetric system and further promoting the practical applications of the liquid lenses.
