Paper Abstract

Electromagnetic forces can be used to deform the free surface of a reflective liquid. Such forces can be obtained through flowing of electrical current in the liquid itself or using its ferro-magnetic properties. For the first approach a ground-based experiment to characterize an adaptive mirror is briefly reported. For the second approach a technique to deploy in nearly- zero gravity environment a large concave mirror is shown. For this space-based application an example of case study is briefly given.
