摘要： Eddy current detection probes and related methods are disclosed. In some embodiments, the eddy current detection probes are hybrid probes, including a solid state sensor and a detection loop. In some embodiments, the eddy current detection probes include a drive coil and a detection loop, with the detection loop having a sensitive axis that is not parallel to principal axis of the drive coil. In some such embodiments, the sensitive axis of the detection loop is perpendicular to the principal axis of the drive coil.

摘要： A fiber-locating structure for aligning an optical fiber includes opposed first and second faces. A first wall, defining a funnel, extends from the first face toward the second face; while a second wall, defining a tunnel, extends from the second face toward the first face. The first and second walls are disposed such that the funnel and the tunnel meet to form a continuous passageway between the first face and the second face.

摘要： An optical switching element for use in an optical cross-bar array, includes a magnetically responsive curtain that switches between an extended state and a deflected state in response to an applied switching-field. The switching element includes a curtain that moves in response to a magnetic field. The curtain has a fixed edge attached to a substrate and a free edge opposite the fixed edge. A first magnetic-field source magnetically coupled to the curtain generates a first magnetic field that urges the curtain into an extended position in which the curtain intercepts the optical beam. A second magnetic-field source, also magnetically coupled to the curtain, generates a second magnetic field that urges the curtain into a deflected position in which the curtain avoids intercepting the optical beam.
