Abstract

Dynamic loading conditions have been used to characterize a polarimetric fiber optic strain gauge developed for integration into structural control systems. The gauge can be used to provide sensor feedback for dyanmic structural control needs in large composite space structures. The optical sensing technique measures changes in polarization state due to strain induced birefringence in an optical fiber. Dynamic strain measurements were made on a vibrating contilevered beam with the gauge and compared to measurements made on the same system using resistive strain gauges that were colocated. Results over the frequency range of 40-500 Hz show excellent agreement between the two gauges. The experimental data also compared favorably with standard vibrating beam theory.
