Reliability, Standardization, and Validation of Optical Fiber Sensors

Abstract

For wider acceptance of optical fiber sensors standardized products are needed with well understood properties and validated performance characteristics, Reliability, availability, maintainability, validation, and standardization of fiber sensors are discussed.

Weldable fibre Bragg grating sensors for steel bridge monitoring

“…The explanation for this fact relies not only on the particularly appropriate characteristics associated with these devices for measuring the most relevant structural parameters, without revealing a number of disadvantages usually attributed to conventional sensors, but also on the growing number of companies operating in the area of fibre optic sensing [3,4]. Even if standardization still seems a little bit far for fibre Bragg gratingbased sensing systems (up to now, only a few isolated efforts are known in this direction [4][5][6][7]), these companies are already offering nowadays an interesting range of sensors based on this technology, as well as several types of measurement units with increasing capabilities. From the point of view of the sensors, important evolutions have been made in terms of parameters that can be measured, packaging oriented to a variety of applications and long-term reliability.…”
