Abstract Liquid crystal lens has the characteristic of variable focal length. Many studies have demonstrated that electronically controlled focusing without mechanical movements can be realized by using liquid crystal lenses in imaging system. In this paper, a four-electrodes liquid crystal lens with a rectangular aperture is applied to focus. The aperture’s aspect ratio of the liquid crystal lens can be designed arbitrarily so that installing it with the periscope lens in phones becomes possible.
