摘要：
A polarization-independent liquid crystal lens that is based on axially symmetric photoalignment is demonstrated. This liquid crystal lens is fabricated by combining radially and azimuthally aligned liquid crystal films with gradient alignments. The configurations of liquid crystals on the substrates are confirmed both optically and using a scanning electron microscope. The focal length of the polarization-independent liquid crystal lens can be controlled by applying various voltages. The device is simple to fabricate, and very convenient to use. It therefore has great practical potential. (C)2011 Optical Society of America
