Abstract

A new optical fiber interferometer is proposed. It realizes the advantage of having a fiber-optic probe desensitized to environmental perturbations. The passage of the reference and sensing beam through the same path in a Sinale-mode optical fiber constitutes the basis of the new interferometer. Two main applications are suggested: Michelson-type interferometer for vibrating target measurements (FOMI) and fiber-optic link noise-free for fiber-optic sensor applications (FOIL). The experimental results point out the high noise-rejection operated by the new scheme compared with a conventional fiber-optic interferometer.
