Abstract
A lens driving device includes a substrate which generates surface acoustic waves on its surface and a movable unit which is coupled to an optical lens and executes translation above the substrate using the surface acoustic waves. The lens driving device can implement translation of the lens without a separate mechanism, unlike the conventional driving devices using motors and screws, thereby satisfying the recent trend towards miniaturization and lightness to be used in a variety of industrial fields that use optical lenses.
