Abstract
An aperture device actuated by a shape memory alloy wire controls two overlapping shuttering surfaces. The two shuttering surfaces control the amount of light transmitted through a lens assembly. The shape memory alloy wire is actuated by a flexible printed circuit which controls a lever slotted to both shuttering surfaces. By Joule heating, the electric current controls the shape of the wire, actuating the aperture device.
