Abstract
An optical apparatus includes an active optical element including an active material encased between a first substrate and a second substrate. Means for selectively controlling the active material in a central portion and a plurality of sectors of the active optical element is employed. The central portion and the plurality of sectors are arranged around an optical axis of the active optical element, wherein the plurality of sectors surround the central portion. A processor of the optical apparatus is configured to generate a drive signal to drive said means to selectively control the active material in at least one of: the central portion, at least one of the plurality of sectors to produce a given optical power thereat.
