Abstract

An investigation was made of magnetomechanical static and dynamic characteristics of spring-type magnetostrictive precision displacement devices based on the Wiedemann effect. It was found that such devices could be used to generate displacements in the range up to 50–100 μm at frequencies up to 1 kHz. The example of a two-coordinate system for automatic control of the position of a reflecting surface was used to demonstrate stable control attainable with the aid of adaptive optics devices.
