Patent ID: 6874897

Claim:
A deformable curvature mirror capable of controlled deformation by applying electrical voltages, comprising: a first plate of an electro-restrictive material with an outer surface and an inner surface; a second plate of an electro-restrictive material with an outer surface and an inner surface, the inner surface of the second plate connected to the inner surface of the first plate; a mirrored surface connected to the outer surface of the first plate; a first conductive layer between the inner surface of the first plate and the inner surface of the second plate; a pattern comprising a first plurality of electrode segments connected to the outer surface of the second plate; a first plurality of unipolar voltage sources for applying variable unipolar electrical voltages to the first plurality of electrode segments; and a second unipolar voltage source connected to the first conductive layer for applying a variable unipolar electrical voltage to the first conductive layer.
