大口径高光焦度电湿润液体透镜研究

Compared with the traditional solid lens, a liquid lens has unique merits such as tunable focal length, low cost and so on. Therefore, it has potential applications in many areas such as military, medicine, scientific research and so on. Even it may replace traditional solid lenses in future. Thus, the liquid lens has become research hotspot. In this project, we plan to carry out scientific research on the theory and technology of liquid lenses. By carrying out the research on structure of liquid lenses and properties of liquid materials and using the methods of optical design and detection, we plan to obtain the theory and methods of increasing optical power and effective aperture of liquid lenses. To exposit mechanism of low driving voltage of liquid lenses，we will make intensive study on electrowetting effect. By proposing theoretical model of electrowetting effect and expositing the mechanism of dielectric layer, liquid materials and driving voltage, we will finally reveal the physical mechanism of decreasing driving voltage. The research work provides the theoretical references for improving optical performance of the liquid lens.
