Title:
OPTICAL FIBER SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/150476
Kind Code:
A1
Abstract:
An optical fiber sensor according to the present invention is provided with a first fixing member at a fixing position provided to a base member, the first fixing member fixing optical fibers to the base member in a state in which a fiber Bragg grating (FBG) part is disposed in each of the optical fiber on one side of the fixing position and the optical fiber on the other side of the fixing position. The optical fiber sensor is also provided with a second fixing member on the one side of the fixing position, the second fixing member fixing the optical fiber to the base member in a state in which a tensile force is applied to a first FBG part. The optical fiber sensor is further provided with a third fixing member on the other side of the fixing position, the third fixing member fixing the optical fiber to the base member in a state in which a tensile force different from that applied to the first FBG part is applied to a second FBG part, and the Bragg wavelength of the second FBG part is different from the Bragg wavelength of the first FBG part.
