Background:
In order to protect danger zones from the consequences of earth intrusion or other geo risks, safety systems are used in which geotextiles are installed.  These building products, which are mainly manufactured using textile technology, are very stretchable and can be used permanently and cost-effectively to reinforce the ground. They are also used as a protective measure against the effects of environmentally hazardous contaminated sites or erosion, as well as for sealing and drainage of landfill sites, waterways or dams and dikes. In the research project "Optical Sensors for Monitoring Earth Structures" innovative and cost efficient sensors based on optical polymer fibers (POF) for structural monitoring of geosynthetics are to be developed and investigated.

About the Talk:
Our sensor system is based on an Optical Time Domain Reflectometer (OTDR). This talk gives an overview about how the system works and how we can infer the location of stretching events on POF from the OTDR data. We investigate and compare two methods, a traditional (CuSUM) and a machine learned (LSTM) approach for this task.
