Abstract
In this paper we present a novel bimorph deformable mirror composed of double-layer lead magnesium niobate (PMN) slices. Compared with lead zirconate titanate (PZT), PMN has better physical features served as bimorph mirror. The optimization design of the mirror electrodes pattern and mirror size are investigated. The type of conductive adhesive and coating process are proposed. An improved mounting apparatus using O-type rubber rings for flexible mounting the mirror is innovated. Also the control circuit model and the interface unit with computer are investigated and designed. A mature design proposal and technology of bimorph deformable mirror system is presented.
