Abstract
We present a nonmechanical zoom lens system based on the Pancharatnam phase effect, which is controlled by the state of circularly polarized light. The device is shown to allow for a compact design for a wide range of zoom ratios. A demonstration system is shown, which has a zoom ratio between its two electrically switchable states. We show its observed image quality experimentally and compare it with calculated expectations.
