Abstract
Light from source (10) is transmitted along an optical fiber (12) to a free end (20). Light emitted from the optical fiber free end is transmitted to a target (22), such as the free end of a second optical fiber (16). An opto-electric transducer (18) provides an output that varies in accordance with the intensity of received light. Relative alignment between the optical fiber free end and the target is controlled by movement of a cantilever beam member (30). The cantilever beam member is a strip of ferromagnetic material (40) extending therealong. A second elongated ferromagnetic strip (42) is mounted closely adjacent but spaced from a free end (36) of the cantilever beam member defining a flux gap (44) therebetween. As magnetic flux flows through the ferromagnetic strips, the beam member free end is deflected in proportion to the strength of the magnetic field.
