Abstract: In this article, a highly sensitive fiber Bragg grating (FBG) axial strain sensing system based on dual loop optoelectronic oscillator (OEO) enhanced by harmonic Vernier effect is proposed ...
Abstract: In this article, a fiber-optic hydrogen sensor based on a cascaded Fabry–Perot interferometer (FPI) structure and vernier effect is proposed and experimented. The sensor is mainly composed ...
