Claim 18:
19. A method of operating an electrowetting liquid lens that comprises a fluid interface between two fluids and a plurality of electrodes, the method comprising:
providing voltages to the plurality of electrodes of the electrowetting liquid lens to curve the fluid interface and to tilt the curved fluid interface, wherein the plurality of electrodes comprise at least four electrodes that extend in a circular fashion about the two fluids, wherein the at least four electrodes cover a continuous circle such that consecutive ones of the at least four electrodes are adjacent each other;
wherein the voltages applied to adjacent ones of the plurality of electrodes of the electrowetting liquid lens are asymmetrical such that the tilted fluid interface has a substantially spherical curvature.
