PURPOSE: An optical fiber inclinometer sensor having a wide measurement range is provided to accurately measure an inclination in an environment in which electromagnetic noise and extreme environmental changes are generated. CONSTITUTION: An optical fiber inclinometer sensor having a wide measurement range comprises a case(110), a pair of single attenuators(120), a pair of single elastic bodies(130), a single mass(140), a reflecting lattice plate(150), and a pair of optical fibers(160). One side of the signal attenuator is fixed to the inner surface of the case. One side of the single elastic body is installed on the other side of the signal attenuator. Both sides of the single mass are fixed to the other side of the single elastic body. The reflecting lattice plate is formed into a lattice form in which a reflecting surface and non-reflecting surface are periodically arranged. The optical fiber irradiates light on the reflecting lattice plate and receives the light reflected by the reflecting lattice plate. |
