INO is supporting research on ferrofluidic deformable mirror (FDM) adaptive optics technologies. INO research activities include development and characterization of FDM as well as development and characterization of high resolution (ExAO) adaptive optics systems using such FDM. The trend towards advanced adaptive optics systems is driving the need for deformable mirrors with a large number of low cost actuators. Liquid mirrors have long been recognized a potential low cost alternative to conventional solid mirrors. We present experimental results updated with a new INO’ FDM prototype (371 actuators, 50 um stroke) as well as theoretical model of surface behaviors.
