Abstract

Disclosed here are methods and systems to vary geometry of an optical lens, so that a single lens can assume various geometries, and change from a portrait lens, to a standard lens, to a wide-angle lens, to a fisheye lens, etc. The lens is made out of piecewise linear elements of polygonal shape, that can move in relation to forcing members laid out on a plane. The forcing members can exert a force on the corresponding piecewise linear elements to cause them to move in relation to the forcing members. The force can be electrical, magnetic, mechanical, etc. As a result, the optical lens can assume various shapes such as concave, convex, and planar.
