Alternatively, the inherent distributed sensing nature of intrinsic fiber optic sensors can be used to create unique forms of sensors for which, there may be no counterpart based on conventional sensor technologies.

In an intrinsic fiber optic sensor, the modulation of the optical carrier induced by the measurand field occurs while the light Cited by:   The discovery of lasers in the s and development of low loss silica optical fiber opened a new era of fiber optic sensors.

Intrinsic insensitivity to electromagnetic interference (EMI), remote detection, operational ability in hazardous environment, and potential for distributed sensing make them especially useful for monitoring large nuclear infrastructures such as coolant monitoring.

SPIEDistributed and Multiplexed Fiber Optic Sensors VI, (27 November ); doi: / Distributed sensing is a technology that enables continuous, real-time measurements along the entire length of a fibre optic cable.

Unlike traditional sensors that rely on discrete sensors measuring at pre-determined points, distributed sensing does not rely upon manufactured sensors but utilises the optical. More geometrically versatile sensor network topologies can also be formed by multiplexing several discrete ‘point’ sensors with common input/output fibres.

This paper reviews this broad and rapidly expanding area of distributed and multiplexed optical fibre sensor technology. The largest interferometric fiber-optic sensor array reported to date consisted of a time and wavelength-division multiplexed architecture combining up to sensors onto a single fiber pair.

Time division multiplexing has been revealed to have low crosstalk and high sensitivity for multiplexing a high number of sensors [99], []. A fiber optic microbend sensor with an elastic, arched sensing diaphragm has been developed for structural strain measurement.

The combination of multiple microbend sensors can form a sensor array for the quasi-distributed sensing application in the monitoring of local strain or deformation along structures, and the optical time domain reflectometry can be conveniently used for interrogation. Current developments in the area of distributed and multiplexed fiber optic sensor systems are reviewed.

In particular, attention is given to intrinsic distributed sensors, quasi-distributed. Water management is a critical mission required to protect the water resources that is essential in diverse industrial applications.

Amongst a variety of parameters such as level (or depth), temperature, conductivity, turbidity, and pH, the water level is the most fundamental one that needs to be monitored on a real-time basis for securing the water management system.
