This article describes the design and operational principle of a new electrically tunable gradient index liquid crystal lens. The lens utilizes linear serpentine electrodes and does not require a semiconductor layer. Experimental results demonstrate that a lens with a 2 mm clear aperture has an optical power of 9.5 diopters and a root-mean-square wave-front error of 0.16 μm. The lens is tested with a miniature camera and the improvement in image quality is experimentally demonstrated.
The design and operational principle of a new electrically tunable gradient index liquid crystal lens are described. The approach is based on linear serpentine electrodes and does not require a semiconductor layer. A preliminary validation is done for a lens with a 2 mm clear aperture, demonstrating 9.5 diopters of optical power and a root-mean-square wave-front error of 0.16 mu m. The developed lens is tested with a miniature camera and the image quality improvement is demonstrated experimentally. (C) 2022 Optica Publishing Group
