Design and analysis of aspherical double-liquid lens based on planar electrode

In order to research an aspherical liquid lens with simple structure and easy realization, the double-liquid based on planar electrode is designed dielectrophoretic effect. The droplet in dielectric electrophoretic polarized electric field move towards direction of higher intensity under action dielectrophoresis forces. With change applied voltage, forces are also changes, thus contact angle at solid-liquid interface changed. Firstly, models different voltages established Comsol software, interfacial profile data exported. Then coefficients surface type fitted obtained Matlab software. Finally, corresponding optical Zemax variable range focal length RMS radius obtained. further characteristics lens, it compared a spherical model. Based theory Gaussian optics theory, relationship between curvature voltage respectively.The material, cavity same as those lens. model according two relational expressions Zemax, value that Thus, spot diagram lenses Then, they results show larger than imaging quality former better latter. Moreover, through device fabrication preliminary experimental analysis resolution can reach 40.318 lp/mm. proposed this paper has which provide new scheme for high-quality its application, expand application
