Switchable Fresnel lens using polymer-stabilized liquid crystals

Opt Express. 2003 Nov 17;11(23):3080-6. doi: 10.1364/oe.11.003080.

Abstract

A switchable Fresnel zone plate lens is demonstrated using a polymer-stabilized liquid crystal. The fabrication process is relatively simple and the device can be operated below 10 volts with fast response time. Such a device works well for a linearly polarized light.
