The number of new adaptive optics applications has soared during the last decade, demonstrating the need for low-cost, high-stroke deformable mirrors with a large number of actuators. Magnetic fluid deformable mirrors (MFDMs) were proposed a few years ago as an alternative to conventional membrane deformable mirrors used in wavefront correctors. Though the idea of these magnetic fluid deformable mirrors is quite recent, they have been appraised by a number of preliminary studies as a promising future technology. This chapter first presents a brief review of the MFDM development history. The operating principle and composition of MFDMs are discussed, including a brief description of important properties of magnetic fluids and metal liquid-like films (MELLFs)—the key constituents of an MFDM. The known advantages, limitations, and potential applications of this new type of deformable mirrors are also discussed, followed by an outline of the research developments presented in the following chapters.
