Abstract
A directable light beam handling device for use in optical communication contains is provided that contains a rotation mechanism with a rotatable ring of soft magnetic material encircling a path of the beam from a beam expander. A mirror or prism being coupled to the rotatable ring is rotated with the ring. The ring includes an array of soft magnetic ridges, forming elevations extending from a surface of the ring. At least three electromagnets are used to drive rotation of the ring around the beam axis. Each electromagnets comprises a soft magnetic yoke, having poles at a first and second end portion of the yoke. The pole at the first end portion faces said surface of the ring, the first end portion having ridges elevated from the yoke in the direction towards the ring, in parallel with the ridges of the ring.
