Abstract:
A deformable curvature mirror capable of controlled deformation by applying electrical voltages, comprising:first and second parallel plates of an electro-restrictive material, said plates having parallel adjacent inner surfaces jointed together with a conductive layer sandwiched between said adjacent inner surfaces, said conductive layer having an electrical terminal connected to electrical ground; said first plate having an outer surface parallel to said inner surface thereof with an unpatterned outer conductive layer on said outer surface and a mirrored surface on said outer conductive layer, said outer conductive layer having an electrical terminal for connected to electrical ground; and said second plate having an outer surface parallel to said inner surface thereof with a pattern of electrode segments on said second plate outer surface, each said segment having a separate electrical terminal for applying a variable electrical voltage thereto for selectively deforming the curvature mirror.
