Paper Abstract

Based on the microbend characteristics of the multimode optical fiber (MMF), a novel twisted fiber torsion angle sensor is demonstrated firstly. The experimental principle and the basic formula have been analyzed and given. The experiment shows that the microbend loss of the multimode optical fiber is sensitive to the torsion angle. In the range of torsion angle from 0 degree(s) to 90 degree(s) the sensitivity is about 1dB/degree. The experimental results are well agreement with the theoretical ones.
