Ryu, Jihee Jang, Mooseok Eom, Tae Joong Yang, Changhuei Chung, Euiheon Optical phase conjugation assisted scattering lens: variable focusing and 3D patterning And detailed calculations and simulation examples are presented to predict how two liquid lenses are related to meet the basic requirements of zoom lenses. The structure and principle of the lens system are introduced in this paper. The liquid lenses, made out of two immiscible liquids, are based on the principle of electrowetting: an effect controlling the wetting properties of a liquid on a solid by modifying the applied voltage at the solid-liquid interface. The lens system consists of a fixed lens and two double-liquid variable-focus lenses. Variable focus photographic lens without mechanical movementsĬhen, Jiabi Peng, Runling Zhuang, SonglinĪ novel design of a zoom lens system without motorized movements is proposed. Furthermore, the liquid lens was applied in a Blu-ray Disc optical recording system to enable dual layer disc reading/writing. We designed and constructed a miniature camera module based on this variable lens suitable for mobile applications. The optical properties of this lens were investigated experimentally. It is demonstrated that two liquids in a tube form a self-centred variable-focus lens. A change in curvature of this meniscus by electrostatic control of the solid/liquid interfacial tension leads to a change in focal distance. The meniscus between two immiscible liquids of different refractive indices can be used as a lens. After optimization, the zoom range of the pseudoaphakic eye greatly exceeds that of normal human eyes, and the spot size on an image plane basically reaches the normal human eye's limit of resolution.Įlectrowetting-Based Variable-Focus Lens for Miniature Systems When the pseudoaphakic eye is built in Zemax, aspherical surfaces are introduced to the double-liquid variable-focus lens to reduce the axial spherical aberration existent in the system. In this work, the crystalline lens in the Gullstrand-Le Grand human eye model is replaced by a double-liquid variable-focus lens, the structure data of which are based on theoretical analysis and experimental results.
