PROBLEM TO BE SOLVED: To provide a lens apparatus with an adjustable focal length. SOLUTION: The lens apparatus includes a non-conductive liquid droplet, which is surrounded by air or immiscible liquids. The non-conductive liquid droplet is placed on a bottom plate. The bottom plate includes a set of first electrodes. The set of first electrodes is disposed in such a way that the set of first electrodes are capable of being selectively biased to respectively create a first electric potential difference between the liquid droplet and each of the set of first electrodes. With the first electric potential differences, a dielectric force is induced, and the profile of the non-conductive liquid droplet is adjustable. COPYRIGHT: (C)2007,JPO&INPIT |
