一种机械驱动式液体可变焦透镜的设计

Design of mechanically-actuated variable focus liquid lens

  • 摘要: 液体可变焦透镜基于仿生学思路,可以不采用任何移动组件,具有变焦能力强,变焦平滑、体积小、质量小,成本低廉、加工容易等特点, 在现代光学仪器中有广泛的应用前景。实现液体可变焦透镜的方法主要有3种。该文采用机械驱动方式设计了一种液体可变焦透镜并对其进行了检测。检测结果表明:该透镜由机械驱动控制液体表面曲率发生变化使透镜焦距变化,焦距变化量与利用光学设计软件分析结果相吻合;将该液体透镜置于普通定焦数码相机前,能调整系统离焦量,实现变焦拍摄,并得到了较好的成像效果。

     

    Abstract: Based on biological vision system, the variable focus liquid lens without any mechanical moving unit has lots of advantages, compared with conventional zoom systems, such as smooth zoom, little volume, light weight, simple fabrication and low cost. Therefore, it will have many potential applications in many fields. The variable focus liquid lens can be realized with three ways. The mechanically-actuated variable focus liquid lens, whose liquid surface curvature is controlled by a stepping motor, was designed and tested. The tested result shows that the variance of the focal length is accordance with the analitical result of CODE V. By putting the liquid lens in front of a fix-focus digital camera, the defocussing range of the system can be adjusted, and the zoom imaging can be realized. Finally the liquid lens has shown a satisfactory effect of imaging.
