Paper Abstract

Using the microbend characteristic of the multimode optical fiber, a novel twisted fiber strain gauge is demonstrated. The experimental principle is analyzed, and the experiment shows that the microbend loss of the multimode optical fiber is sensitive to the distortion. The sensitivity is 3.5dB /?? . The experiment results agree well with the theory.
