Abstract:Optical magnetic field current sensors could overcome the shortcomings of traditional sensors based on electrical principles, such as large volume, insufficient sensitivity, and limitations of working environment, which can be applied to medical, military, and other fields with higher sensing requirements. We demonstrated experimentally the inscription of the long-period fiber gratings (LPFGs) in the thin-cladding fiber (TCF). The magnetic field current sensor is fabricated by encapsulating the TCF–LPFG with m… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
