ABSTRACT:
The scanner includes a first spring plate and a second spring plate of common size and shape symmetrically aligned and spaced. A first reflective surface is located at an end of first spring plate. A counter balance mass is located at a corresponding end of the second spring plate. The first spring plate and counter balance mass have common mass and volume and are symmetrically aligned about an axis of symmetry. During a drive cycle, the first spring plate and second spring plate are deflected equally in opposite directions. The first reflective surface and counter balance mass move equally in opposite directions causing the respective movement of the first reflective surface to be counter balanced by the movement of the counter balance mass. The motion is driven by electromagnetic circuits or piezoelectric circuits.
