Fiber-optic sensors - An overview

Fiber-optic sensors are well suited for the measurement of a variety of physical quantities. Mechanical parameters like force, pressure, path length, velocity, acceleration, rotation rate, vibration, flow rate, filling level, bending, and mechanical strain up to breakage, can be measured. There are sensors for measurement of electric and magnetic fields as well as fluorescence, concentration, ph-value, and furthermore temperature, refractive index, and sound.
