From an industrial point of view, fiber optic sensors are attractive because they offer excellent sensitivity and dynamic range, compact and rugged packages, and potential for low cost and high reliability. In the chemical or pyrotechnic industries where explosion hazards exist, fibers can be run anywhere, unlike electrical cables, without the need for protective conduits, ground-fault protectors, or explosion-proof containers. Aerospace applications of fiber sensors have provided initial and continuing strong impetus for development via US government funding. A number of fiber optic methods have been used and some commercialized for industrial temperature measurements. Fiber optic sensors for pressure measurement have undergone extensive development, especially for acoustic applications in the US Navy's Fiber Optic Sensor System program. Various fiber optic intensity-based methods are used to measure position as well as proximity and displacement. REFERENCES K.
