摘要：

A novel optical fiber sensor used for remote monitoring of salinity in water is proposed. Based on the detection of beam deviation due to the refractive index changes of the salt water, salinity can be measured by a position-sensitive detector. The measurement principle is theoretically described. Preliminary prototype is set up, and experimental results indicate the feasibility of the method. Salinity measurement resolution can reach 0.012parts per thousand within the measurement range from distilled water to salt water with salinity of 50parts per thousand.
