Title: Optical fiber magnetic sensor
Inventor: MIYAZAKI JUNPEI
IPC: G01R33/032
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a reliable optical fiber magnetic sensor of good frequency responsivity and sensitivity and excellent environment-resistance, such as temperature and vibration. SOLUTION: A stress is larger at a curved part of a metal-coated optical fiber 13 than at a straight part. The curved part of the metal-coated optical fiber 13 is resonated by longitudinal wave of propagated sound wave where the optical fiber itself which is estimated as almost rigid body is a medium. Thus, even the same dimension as conventional straight sensor provides much higher resonance frequency for wider measurement range. Flowing of an AC current of high frequency corresponding to measurement range in a closed circuit comprising an AC power source 15, a conductive wire 16, and the metal- coated optical fiber 13 realizes it. Since resonance frequency is decided by magnitude of stress, smaller bending radius causes higher resonance frequency with the same optical fiber resulting in improved frequency responsivity.
