The aperture of traditional liquid crystal lens is usually only several hundred microns,which greatly limits its application.If the aperture of the liquid crystal lens can be enlarged,the liquid crystal lens will be more widely used.In the paper,a liquid crystal lens with a new type of electrode pattern is designed.The structure of this lens is similar to Fresnel lens.The electrodes of the whole lens are divided into upper and lower layers,the upper layer electrodes are designed into several concentric annular groups,and the lower layer ele...
