Abstract
A new type of adaptive mirror is briefly presented. A thin film of ele ctrically conductive, reflective liquid (like mercury) is affected by a stabilized current, while a variable magnetic field is produced at i ts bottom surface by a number of adjustable current coils (actuators). A demonstration of the technique has been experimentally carried out using a Michelson interferometer. The first results are here briefly d escribed.
