Electric-field-driven　liquid　crystal　(ELC)　lens　with　tunable　focal　length　and　their　depth　of　field　has　been　extensively　applied　in　3D　display　and　imaging　systems.　In　this　work,　a　dual-layer　electrode-driven　liquid　crystal　(DELC)　lens　with　electrically　tunable　focal　length　and　controllable　focal　plane　is　demonstrated.　ITO-SiO2-AZO　electrodes　with　the　dual-layer　staggered　structure　on　the　top　substrate　are　used　as　driven　electrodes　within　a　LC　cell,　which　permits　the　establishment　of　an　alternative　controllability.　The　focal　length　of　the　DELC　lens　can　be　adjusted　from　1.41　cm　to　0.29　cm　when　the　operating　voltage　changes　from　15　V　to　40　V.　Furthermore,　the　focal　plane　of　the　DELC　lens　can　selectively　move　by　changing　the　driving　method　of　the　applied　voltage　to　the　next　driven　electrodes.　This　work　demonstrates　that　the　DELC　lens　has　potential　applications　in　imaging　systems　because　of　electrically　tunable　focal　length　and　controllable　focal　plane.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
