5. Introduction
Fiber Optic Sensors (FOS) for Structural Health Monitoring (SHM) have moved from R&D to mainstream applications
Some technologies have emerged as dominant:
SOFO: Long-gauge deformation sensors
FBG’s: Point Strain and Temperature sensors
Brillouin and Raman scattering: distributed Sensing
Standards and interoperability are emerging, allowing combination of FOS and traditional sensors in the same projects

6. SOFO Sensors Advantages:
Long-gauge: not sensitive to local changes. Enables monitoring at the scale of structural elements
Built-in temperature compensation
Very accurate: sub-microstrain
Long-term stable
Track record of more than 10’000 sensors installed over 15+ years

7. SOFO System Long-gauge fiber optic deformation sensors
Gauge length of 0.2m to 10m
High resolution: 2µm
Excellent long-term stability
Insensitive to temperature, EM fields, corrosion,...
Embeddable or surface installable in new and existing structures
Easy and rapid to install and measure
Ideal for monitoring of large structures, especially concrete, and geotechnical applicaitons

8. MuST Sensors Advantages: Variety of sensing parameters and conditions
Strain on metals, composites, concrete…
Temperature
Tilt
Accelleration
Mulitplexing
Accuracy and stability

9. Fiber Bragg Grating Sensors

10. MuST System
Multiplexed Strain and Temperature monitoring system based on Fiber Bragg Gratings
Up to 10 strain sensors and 25 temperature sensors on the same line
Gauge length from 1 cm to 2 m
Temperature measurement for strain and deformation sensors
Static and dynamic measurements possible

11. SOFO and MuST (FBG)
SOFO and FBG: two leading fiber optic sensing technologies for SHM
SOFO offer superior performance and flexibility in monitoring deformations of large structures. In particular well adapted to measure deformations of concrete, rock and soil.
SOFO has lower sensor costs
MuST (FBG) offer sensors for different parameters
MuST (FBG) sensors can be multiplexed in-line
In real-world applications it would be ideal to use sensors based on both technologies in the same project

14. SOFO VII technology
Sophisticated algorithms allow measurement of SOFO sensors through spectral analysis.
FFT

15. SOFO VII MuST Features Two formats: Each channel can measure either:
Portable (4 channels)
Permanent installation (4 or 8 channels)
Each channel can measure either:
1 SOFO sensor
Up to 5 SOFO sensors, using external 1x5 splitter
1 chain of FBG sensors (e.g. 7 deformation, 12 strain, 25 T)
Up to 4 chains of FBG sensors, using external 1x4 coupler
Each Channel can be SW configured for SOFO or MuST
Integrates field PC with SMARTEC software engine and user interface
