Abstract: INO supports research on Ferrofluidic Deformable Mirror (FDM) adaptive optics technologies and, as such, its research activities include the development and characterization of FDM and high resolution (ExAO) adaptive optics systems using such FDMs. Liquid mirrors have long been recognized as a potential low-cost alternative to conventional solid mirrors. Since the trend is towards advanced adaptive optics systems, a need for deformable mirrors with a large number of low-cost actuators exists. This paper presents updated experimental results using a new INO FDM prototype (271 actuators, 5O µm stroke) as well as a theoretical model of surface behaviors.
