TUNABLE LIQUID MICROLENS WITH LUBRICATION ASSISTED ELECTROWETTING

摘要

A tunable liquid microlens includes an insulating layer, a droplet of a transparent conducting liquid, and a lubricating layer disposed on a first surface of th e insulating layer and between the droplet and the insulating layer. The microlens also includes a plurality of electrodes insulated from the droplet by the insulating layer a nd the lubricating layer, the plurality of electrodes being disposed such that they may be selectively biased to create a respective voltage potential between the droplet and each of the plurality of electrodes, whereby an angle between the droplet and a plane parallel to the first surface of the insulating layer may be varied and the droplet m ay be repositioned relative to the insulating layer.
