Paper Abstract

We report simultaneous salinity/saccharinity and temperature measurement with a fiber Bragg grating (FBG)-based sensor system. By adopting multiplexing technique, the sensor system consists of two FBG sensing elements in which one FBG is sensitive to salinity/saccharinity while the other one sensitive to temperature only. Experiments indicated that the salinity, saccharinity, and temperature sensitivities of the polyimide-coated grating were 0.0165 nm/M (blueshift), 0.0012 nm/°Bx (blueshift), and 0.0094 nm/°C (redshift), respectively. The temperature sensitivity of the acrylate-coated FBG was 0.0102 nm/°C (redshift).
