Abstract
A method that comprises returning a droplet of conducting liquid of a tunable liquid microlens to a calibration position. Returning the droplet includes applying a first set of voltages between the conducting liquid and a first set of electrodes to move the droplet to a different position than the calibrated position. Returning the droplet further includes applying a second set of voltages between the conducting liquid and a second set of electrodes to return the droplet to the calibration position.
