Fiber Optic Chemical Sensors
Provide a means to detect the presence of specific chemicals in various forms and solutions, and can be used in industrial process (real time) control, exhaust stacks, groundwater, etc. They operate by analyzing changes to the light spectrum as the sensor probe interacts with the surroundings. SRS has developed a number of complete sensor systems based on sol-gel colorimetric indicators, a new class of composite materials which change color in the presence of certain chemicals, and Raman spectroscopy.
