High-noise-rejection fiber-optic probe for interferometric applications.
A fiber-optic interferometer with almost total rejection of the noise introduced by the fiber-optic link is reported. The new scheme is based on the passage of the reference and sensing beams through the same path in a single-mode fiber. The experimental results emphasize the excellent noise rejection of the new setup compared with that of a conventional fiber-optic interferometer.
