Abstract
A liquid lens structure has an adjustable and continuous range of optical power. The liquid lens structure comprises a substrate layer and a deformable membrane which enclose a volume of liquid. The substrate layer is at least partially transparent in the optical band. The deformable membrane comprises a ground layer, two membrane layers, and two conductive layers. Each of the two conductive layers control electrical voltage applied to one of the membrane layers in reference to the ground layer, wherein each membrane layer deforms in response to applied electrical voltage. The deformation of the two membrane layers adjusts a curvature of the deformable membrane which provides the adjustable continuous range of optical power to the liquid lens structure.
