Abstract

An alternative approach to compact deformable mirrors for adaptive optics is developed. A prototype of a two inch mirror composed of a thin polymer membrane covered with a matrix of permanent magnets and an array of microcoils was built. Several complementary modelling tools were used to study the behaviour of the device. Promising first results show regular deformations of up to 20 μm, a good linearity and a bandwith of 200 Hz. This novel technology should enable higher resolution with smaller, lighter integrated mirrors
