Electrostatic deformable mirror with moving substrate

Inspection light of funduscopy is warped by distortion of eyeballs and atmospheric vibration. So it’s required to correct the wavefront instantly and accurately. For this, deformable mirrors (DMs) that can correct wavefront by reflecting the light are widely utilized. Our lab suggested a new DM, which can realize large displacement. In this study, I establish fabrication process of the DM, fabricate it and build a simple mathematics analysis model to control a shape of the DM.
