Study of surface modes on a vibrating electrowetting liquid lens

Matthias Strauch, Yifeng Shao, Florian Bociort, H. Paul Urbach


The increased usage of liquid lenses motivates us to investigate surface waves on the liquid's surface. During fast focal switching, the surface waves decrease the imaging quality. We propose a model that describes the surface modes appearing on a liquid lens and predicts the resonance frequencies. The effects of those surface modes on a laser beam are simulated using Fresnel propagation, and the model is verified experimentally.
