Abstract: An optical system includes a circular lens having a first set of electrodes arranged in a concentric pattern and a liquid crystal material in electrical communication with the first set of electrodes. The optical system also includes a first cylindrical lens having a vertical meridian and a second set of electrodes oriented along an axis parallel to the vertical meridian. The optical system additionally includes a second cylindrical lens having a third set of electrodes oriented at an angle with respect to the axis.
