In this dissertation, a framework is developed and demonstrated for the use of a new shape measurement system consisting of fiber Bragg grating (FBG) based strain sensors, a shape determination algorithm based on Frenet frames, and a signal processing algorithm based on modal analysis techniques. The system is experimentally validated by using a long slender, aluminum cantilever structure (65.625″x2.0″x0.125″) with eight serially multiplexed FBG sensors. The multiplexed FBG sensors measure the bending strain distribution along the cantilever structure…
