Abstract
Magnetic-fluid deformable mirrors (MFDMs) offer a simple alternative to the costly yet inefficient wavefront correctors currently in use in adaptive optics (AO) systems. They have been found particularly suitable for AO systems used in ophthalmic applications, such as retinal imaging. However, their practical implementation in clinical devices is contingent on the development of effective methods to model and control their surface-shape. This article presents a model of the dynamic response of the surface of a MFDM to the applied magnetic field. The resulting model allows the development of high-performance shape control algorithms for the mirror surface.
