Abstract: A liquid lens system includes first and second liquids disposed within a cavity. An interface between the first and second liquids defines a variable lens. A common electrode is in electrical communication with the first liquid. A driving electrode is disposed on a sidewall of the cavity and insulated from the first and second liquids. A controller supplies a common voltage to the common electrode and a driving voltage to the driving electrode. A voltage differential between the common voltage and the driving voltage is based at least in part on at least one of: (a) a first reference capacitance of a first reference electrode pair disposed within the first portion of the cavity and insulated from the first liquid or (b) a second reference capacitance of a second reference electrode pair disposed within the second portion of the cavity and insulated from the first liquid and the second liquid.
