Mechanism of Focus-Variable Liquid Lens Driven by Bending Vibration of Thin Films
A novel structure for the focus-variable liquid lens driven by the bending vibration of thin films is proposed, and the mechanism of this proposed novel lens is theoretically analyzed and experimentally investigated. The results show that, under the driving of the bending vibration of the thin films, the pressure in this proposed lens is large in its center and small in its edge, which indicates that this lens is a convex lens. Meanwhile, its focal length decreases with the increase of input voltage, and the focal length range is 10-60 mm. This proposed lens has a simple and thin structure, and a larger zoom range than that of other liquid zoom lenses, and thus has the strong practical application value.
