Abstract

A structure of a fiber-optic refractometric sensor for ethanol concentration measurement is proposed, based on a phase-shifted fiber Bragg grating (π-FBG) and a two-frequency probing method. The sensor implements a parallel measurement scheme, allowing simultaneous determination of temperature and effective refractive index of the environment.
