Abstract
An optical fiber sensor according to the present invention is provided with a first fixation member which fixes an optical fiber on a base at a fixation position set on the base in a state where FBGs are arranged in one side of the fixation position and the other side of the fixation position respectively. Also, in one side of the fixation position, a second fixation member which fixes the optical fiber on the base in a state where tension is applied to a first FBG is provided. Further, in the other side of the fixation position, a third fixation member which fixes the optical fiber on the base in a state where tension which is different from the tension applied to the first FBG is applied to the second FBG and the Bragg wavelength of the second FBG is different from that of the first FBG is provided.
