Abstract
This article presents an analytical model for the dynamic surface shape of a magnetic fluid deformable mirror (MFDM) in cylindrical coordinates. Such a mirror is proposed as a high-performance alternative to existing costly and fragile wavefront correctors in ophthalmic adaptive optics systems. Results of an experimental investigation aimed at validating the developed analytical model are also presented. A novel approach to linearize and amplify the response of the MFDM surface to the applied magnetic field is introduced and experimentally validated. The developed model will make it possible to design effective surface shape control algorithms for the mirror.
