Paper Abstract

Fiber Bragg gratings are of particular interest for distributed sensor applications such as embedded sensors for structural strain monitoring. This paper discusses the use of a wavelength division multiplexed fiber Bragg grating array for structural shape sensing and vibrational mode analysis. The gratings are surface attached to a cantilever beam and demodulated by a scanning fiber Fabry Perot filter to obtain strain information at different locations along the structure. A PC is used to read the strain information and perform static shape modeling of the beam.
