Modal analysis of liquid-solid coupling liquid lens

摘要

Liquid lens of fast focusing is valuable to be researched for the application in instruments of miniature. According to many researchers achievement in this field, the fast focusing mechanism of liquid lens is firstly present. Then the oscillation modes of the liquid-solid coupling liquid lens in different capillary tube cases are analyzed in this paper. For better understanding of the fast focusing mechanism and its influencing factors, finite element models of the water droplet lens are set up in ANSYS, and the former four oscillation modes are solved to analyze the relative influencing relations. The work in this paper will lay a foundation for the further research on the liquid lens of fast focusing.
