 Central aim of organisation
Development of Structural Health Monitoring systems using embedded fiber optic sensors and external sensors

 Briefly describe your organisation
We develop and implement Structural Health Monitoring systems for man-made structures (bridges, dams, railway lines ...) and natural phenomena (landslides, ...). We currently monitor 24/7 one of the largest landslides in Austria using GPS sensors on the surface and embedded fiber optic sensor within the landslide. We have great experience in the development of fiber optic sensors and have them installed in concrete structures (bridges), embedded in soils and used to monitor strain within railway tracks and railway sleepers.
We are also active within robotics where we provide external control by tracking moving objects like UAVs with total stations with laser based methods and pattern recognition.

 RTD Experience
We are using fiber optic sensors for the measurement of temperature and strain for more than 10 years and have developed several calibration facilities in our measurement lab.

Currently we are in the management committee of the COST Action TD1001: Novel and Reliable Optical Fibre Sensor Systems for Future Security and Safety Applications (OFSeSa) .

We are also chair of the FIG Study Group 6.2.1.Fibre Optic Sensors.

We have successfully developed fiber optic strain pads for railway applications in an FFG project and a proven record in the monitoring critical infrastructure (bridges, railway lines, ...) and the monitoring of landslides.

We have developed software for total stations to track UAVs and robots to determine high accurate reference values of the trajectories based on laser based measurements and pattern recognition.
