1.1 Fiber optic sensors on the rise

Metrology-related sciences and technologies have led to the development of a large number of measuring devices covering a wide range of applications. Among these, the characterization of the mechanical and chemical properties of a system or medium occupies a significant place. The measurement and control of pressure, stress, displacement, acceleration, velocity and vibration are widely demanded, if not required, in the industrial world. Mechanical properties are indicators of the health of machines (turbines, motors, transformers, etc.), vehicles (cars, aeronautics, space shuttles, etc.) and civil engineering structures (bridges, oil platforms, architecture, dams, etc.). The metrology of mechanical properties helps to meet maintenance needs: continuous...
