摘要：
To realize three dimensional image resolution enhancement, focus tuning and beam angle tilting via use of electrowetting-on-dielectric (EWOD) liquid microlens has been reported in this paper. The lens comprises four control electrodes on a glass substrate, two spherical liquid lenses with different refractive indices, and an encapsulation polymer. Focus tuning can realized via lateral shift of the inner lens and change in refractive curvature of the liquid lens. As observed, focus tuning over distances in the range of 9.3-29.3 mm can be realized. Correspondingly, tuning range of tilt angle was observed to be of the order of +/- 2.13 degrees.
