The present invention relates to an optical fiber magnetic scanning arrangement for a miniature optical fiber probe and can be applied for optical beam delivery in various optical imaging techniques. The arrangement is of the type where an optical fiber is rigidly fixed to a current conductor and serving as a flexible cantilever with a capability for the distal part of the optical fiber of being deflected in a direction substantially orthogonal to its own axis. New designs of the magnetic system are less critical to the shape and dimensional tolerances of scanner elements and assembly. These designs provide a potential for a less difficult assembly process and for further miniaturization. According to one aspect of the invention the permanent magnet system includes at least a first permanent magnet with a magnetization direction that is substantially aligned with the own axis of the optical fiber. The current conductor loop is placed adjacent to the one of the end faces of the first permanent magnet. According to another aspect of the invention the permanent magnet system includes at least a first permanent magnet piece with a magnetization direction that is substantially orthogonal to the own axis of the optical fiber. The permanent magnet piece extends in a direction substantially aligned with the own axis of the optical fiber and has an inner surface, the current conductor loop being adjacent to at least a part of the inner surface of the first permanent magnet piece. According to another aspect of the invention the permanent magnet system includes a permanent magnet of a hollow cylinder type with a substantially radial magnetization direction. The permanent magnet cylinder extends in a direction substantially aligned with the own axis of the optical fiber. The current conductor loop is placed inside the permanent magnet cylinder. A miniature optical fiber probe, which incorporates the optical fiber lateral scanner of the invention, will inherit all its benefits.
