Condition monitoring of heavy electromechanical equipment is commonly accomplished in the industry using vibration analysis.
Several techniques, mainly based on capacitive and piezoelectric accelerometers, have been applied for predictive maintenance.
However, the negative influence of the electromagnetic interference (EMI) can be a real problem when electrical signals are used
to detect and transmit physical parameters in noisy environments such as electric power generator plants with high levels of EMI.
Optical fiber sensors are increasingly used because of the nonelectrical nature of signals. In this paper, the most frequently used
vibration optical fiber sensors will be reviewed, classifying them by the sensing techniques and measurement principles. The main
techniques, intensity modulation, fiber bragg gratings and Fabry-P´erot Interferometry, will be reviewed here. [--]
