Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide an optical vibration sensor whose change with the passage of time is made extremely small and in which the vibration direction of a vibrator is arranged at right angles to an optical fiber. SOLUTION: A laser beam which passes an optical fiber 12 passes an optical waveguide 2. It is radiated by an optical lens 3 in a diffraction grating perpendicularly or nearly perpendicularly to its face. It is reflected by the first light reflecting face 4 of a cantilever 5. It is returned again to the optical lens 3. It is returned to the optical fiber 12 via the optical waveguide 2. When a vibrator to be detected is vibrated, also the cantilever 5 in a sensing part which is bonded and fixed to the vibrating body is vibrated, and the coupling amount of the laser beam which is reflected by the first light reflecting face 4 of the cantilever 5 so as to be incident again on the optical lens 3 is changed according to its vibration.  The laser beam or the like which is reflected by the end face of the optical lens 3 so as to be returned to the optical fiber 12 has almost nothing to do with the vibration of the vibrator to be detected, and the returned laser beam is used as reference light.
