FIBER OPTIC TECHNOLOGIES

FIBER OPTIC TECHNOLOGIES 19

Fiber Optic Technologies Fabry-Perot Interferometer (FISO):

These point sensors measure local strain, temperature, pressure and displacement. These values are encoded in a change of length of an optical cavity within the sensors that can be measured accurately. Fabry-Perot sensors offer an excellent long-term stability. They are the ideal optical replacement for conventional geotechnical sensors.

Low-Coherence Interferometers (SOFO):

These long-gauge sensors measure displacement or average strain over measurement bases that can extend up to several meters. They are ideal transducers for monitoring concrete and geotechnical structures. Deformations are measured by observing the length changes of an optical fiber attached to the structure under observation, compared to a loose reference fiber. This measurement principle allows accurate and stable measurements and insensitivity to temperature variations.

Fiber Bragg Grating (MuST):

FBG sensors are written in the optical fiber core and act as optical filters, reflecting the wavelength that matches the grating pitch. The reflected wavelength depends on the strain and temperature of the grating, enabling measurement of those two parameters and others that can be transformed to strain (deformation, tilt and acceleration). It is possible to combine multiple gratings with different reflective wavelength on the same fiber (multiplexing).

Distributed Raman Scattering (DiTemp):

These sensors use an intrinsic property of optical fibers to measure the local average temperature of each meter of fiber for lengths up to several tens of kilometers. This enables the measurement of thousands of temperatures along a single cable. This technology is particularly suitable for detecting and localizing hot or cold spots associated with leaks or other defects.

Distributed Brillouin Scattering (DiTeSt brand):

This technology is similar to Raman scattering, but offers the additional ability to measure distributed strain. This enables the detection of local events such as settlements, deformations, cracks and movements.

FIBER OPTIC SOFTWARE

DIVIEW II & DIVIEW LITE SOFTWARE

The Distributed Data Management and Analysis Software DiView is designed for data storing, processing, representation and analysis, as well as for the control of single or multiple DiTeSt and DiTemp reading units. The main functions of DiView software are aimed to measure sensors automatically. The operator can view in real time the measurements and the alarms on one or multiple maps/graphs. DiView is also able to trigger alerts for different types of events, including: Strain, Temperature, Leakage and Crack.

SDB SOFTWARE

SDB offers a unified tool for measurement and monitoring data acquisition and management. The SDB software package is designed to manage the acquisition, storage, analysis and visualization of static data from fiber optic and conventional sensors. It is compatible with all SMARTEC and Roctest data acquisition units. All data is acquired automatically at pre-defined intervals and stored in a unique relational database. The data can be used to generate alerts based on complex multi-sensor criteria and the software allows the interface to other external systems such as SCADA.

FIBER OPTIC SOFTWARE

SDB PRO SOFTWARE

SDB View is part of the SDB suite. It enables easy data navigation and visualization of measurements and an SDB database. SDB View enables a simultaneous display of multiple user-defined views on sensors chosen from the database over a defined monitoring period. The display can be in form of a map, a table or a graph plot with associated options such as thresholds plot, colors and sounds on alert criteria. New views can be generated by the user without any programming and can be exported in different formats for further analysis or publishing.

SDB VIEW SOFTWARE

The SDB Pro software is part of the SDB software suite. It simplifies data interpretation, visualization and analysis using real-time calculated virtual sensors called macro-sensors. The value of a macro-sensor is obtained by applying user-defined mathematical functions to the measurements data from real sensors or other macro-sensors, and is stored in an SDB database. The definition of macro-sensors is performed using a user-friendly interface. The representation and properties of this sensor are the same as those of real sensors, i.e. they can be visualized in tables and diagrams and used in alarm criteria.
