FOSs are resistant to electromagnetic interference, corrosion, and high-strain cyclic loading while also providing significant reductions in weight and the complexity of installation when compared to conventional electrical resistance foil strain gauges (FSGs). This paper builds on previous benchmarking of proprietary distributed FOSs and demonstrates a FOS-based high-density strain measurement capability on a large aircraft structure subjected to representative flight loading.
