Title: Hybrid Diffractive-refractive Liquid Lens for Variable-focus Optical System
Abstract: The hybrid diffractive-refractive variable-focus liquid lens composed of a liquid refractor and a binary optical lens is demonstrated in this letter. The focal length adjustment is achieved by changing the radius of curvature of the refractive lens without any mechanical moving parts. The main advantage of the lens is that it could account for the chromatic aberration when the shape of the liquid lens is changed. Finally, a model of the hybrid diffractive-refractive variable-focus liquid lens is designed,showing that it is excellently suited for use in portable applications.
