Single-Crystal PMN Bimorph Deformable Mirrors
Introduction
This project is focused on characterizing and modeling MEMS deformable
mirrors for adaptive optics. We are interested in improving both the
design and control of these mirrors as well as in developing new
characterization and wavefront sensing methods. Although this project is
presently targeted towards the vision science applications of adaptive
optics, we are also interested in other applications requiring high-speed
correction.
A MEMS-based deformable mirror constructed using single-crystal PMN-PT for use in ophthalmologic adaptive optics is presented. The fabrication process and the results of characterization of the DM are described. A large stroke and high operating bandwidth assure that the DM can be a promising wavefront corrector.
