Deformable curvature mirror with unipolar wiring |
摘要 |
A deformable curvature mirror capable of controlled deformation by applying unipolar electrical voltages to electrode segments on the back of the mirror. Two plates of an electro-restrictive material, such as PZT or PMN, are jointed together. One plate has a pattern of a plurality of electrode segments on the outer surface with each electrode segment having a separate electrical terminal for applying a variable unipolar electrical voltage thereto for causing variable expansion of the plate and thereby selectively deforming that plate and, in turn, the deformable curvature mirror.
