Optical fiber based sensors for targeted salt detection and monitoring

RESEARCH GOALS
 Design salinity sensors capable of measuring low salt (NaCl)
concentration in water
• Identify and test salt specific fluorophores and polymer coatings;
testing durability, sensitivity and specificity
• Build the sensors with robust packaging
• Test the sensors in a laboratory set-up that mimics the changes
in physical and chemical conditions in an aquifer
• Comparison studies among various approaches
• Test the FBG-based refractive index sensor in the field and
assess long-term survivability
