ABSTRACT:
An optical device includes a housing having first to fourth sidewalls and top and bottom plates; and (M−1) partitions between the first and second sidewalls, and has M lens chambers, each filled with first and second liquids forming a liquid lens. A first lens chamber is defined by the first, third, and fourth sidewalls, first partition, and top and bottom plates. The top plate, first sidewall, and first partition respectively have first to third electrodes. An (m+1)-th lens chamber is defined by an m-th partition, third sidewall, (m+1)-th partition, fourth sidewall, and top and bottom plates, m being 1, 2, . . . , or M−2. The top plate, m-th partition, and (m+1)-th partition respectively have first to third electrodes. An M-th lens chamber is defined by an (M−1)-th partition, second to fourth sidewalls, and top and bottom plates. The top plate, (M−1)-th partition, and second sidewall respectively have first to third electrodes.
