  • Device for measuring rotational speed using an optical fiber sensor
    Patent number: 5204619
    Abstract: A device for measuring the rotational speed of a shaft. A toothed wheel is connected to rotate with the shaft within a magnetic field. A birefringement optic fiber is connected to a light source, and passes through the magnetic field. A magnetorestrictive material is supported in contact with the optical fiber and produces stress on the optical fiber in response to magnetic flux variations. Light emerging from the optical fiber is analyzed with respect to its change in phase to determine the periodic variation in the magnetic field caused by the toothed wheel.
