Abstract :
An intensity-based fiber optic sensor (FOS) head, which consists of a rectangular pulse train shaped steel wire and an optical fiber, is proposed and applied to the measurement of FRP coupon strain. The measured data for FRP coupon strain are compared with those of a commercial FBG sensor and a strain gauge. The measured results show that the self-referencing intensity-based FOS with the proposed FOS head has good performance to measure the FRP coupon strain.
