Paper Abstract

A novel fiber optic sensor for simultaneous measurement of temperature and salinity with multiplexed polymer-coated fiber Bragg gratings is demonstrated. It has been found that the polyimide-coated fibre Bragg grating respond to variations of both temperature and salinity while the acrylate-coated fiber Bragg grating is only sensitive to the environmental temperature. The experimental results showed that the temperature and salinity sensitivities of the multiplexed fiber Bragg grating sensor are 0.0102 nm/°C and 0.0038 nm/%S, respectively.
