Deformable mirror is used in adaptive optics for retinal observation with higher resolution. it is necessary to control the shape of the mirror surface about 10 mm in diameter within the range of maximum displacement of about 3 μm. We proposes a new structure that realizes convex deformation and low voltage driving and we are working on research to realize it.
