Abstract: An example embodiment may include an interferometer. The interferometer may include a multimode waveguide with an input waveguide optically coupled to a first side of the multimode waveguide, for feeding a light signal to the multimode waveguide. The interferometer may also include a first waveguide at one end optically coupled to a second side of the multimode waveguide, and at the other end terminated by a first waveguide mirror. The interferometer may also include a second waveguide at one end optically coupled to the second side of the multimode waveguide and at the other end terminated by a second waveguide mirror. The multimode waveguide may be adapted to distribute the light signal towards the first and second waveguide mirror via the first waveguide and via the second waveguide.

Abstract: A detector for oil condition monitoring includes an optical fiber having a first end and a second end having an end face. A sensor body has a gap in which a sample of the oil may be received and a reflecting surface, the second end of the optical fiber being embedded in the sensor body and having an end face spaced from the reflecting surface across the gap. Light emitted from the optical fiber can pass through the sample of oil and be reflected by the reflecting surface back into the optical fiber. By interferometry of the respective signals, the condition of the oil can be determined.
