Fully distributed optical fiber strain sensor with 10-12 ε/√Hz sensitivity

Advanced optical fiber reflectometry techniques enable spatially distributed measurements of true relative deformations over the length of a conventional optical fiber cable. This methodology is attractive for many applications ranging from intrusion monitoring to seismology. However, accurate quant...
