摘要

PURPOSE: An FBG(Fiber Bragg Grating) sensor having a zigzag-type leaf spring fixing member, a biaxial FBG sensor having a zigzag-type leaf spring fixing member, and a manufacturing apparatus and method for the FBG sensor are provided to prevent damage to an FBG sensor caused by excessive prestrain when attaching the sensor to a structure and to ensure easy installation of the sensor on a structure. CONSTITUTION: A method for manufacturing an FBG sensor having a zigzag-type leaf spring fixing member is as follows. A first fixing part(130) of a zigzag-type leaf spring is fixed to a first fixing jig and a second fixing part(140) is fixed to a second fixing jig. The second fixing jig is linearly moved toward the first fixing jig so that the zigzag-type leaf spring is compressed. An optical fiber cable(160) is inserted into a slit(150) and fixed with an optical fiber fixing adhesive. The second fixing jig is linearly moved opposite to the first fixing jig after curing the adhesive so that the compression of the zigzag-type leaf spring is released.
