Paper Abstract

An alternative approach to more compact deformable mirrors for adaptive optics is developed. A thin and flexible reflective membrane is coated with a magnetic layer and locally deformed by the field created by an array of planar microcoils. This novel technology should enable higher resolution with smaller, lighter integrated mirrors. Several complementary modeling tools are used to study the electromagnetic, mechanical, magneto-mechanical and thermal behavior of the device. A first prototype of (phi) 30 mm mirror with a matrix of permanent magnets and an array of 25 microcoils is under construction.
