Abstract
A tunable microlens uses a layer of photo-conducting material which results in a voltage differential between at least one of a plurality of electrodes and a droplet of conducting liquid when a light beam is incident upon the photo-conducting material. Such droplet, which forms the optics of the microlens, moves toward an electrode with higher voltage relative to other electrodes in the microlens. Thus, for example, when the light beam is misaligned with the microlens, the voltage differential causes the droplet, and hence the microlens, to realign itself with the beam.
