TY - GEN A1 - Habel, Wolfgang A1 - Schukar, Vivien T1 - Reliability issues when using fibre optic strain sensors for materials investigations and structural monitoring N2 - Reliable measurement results with fibre optic sensors require profound knowledge of physical mode of function, of materials used and appropriate application. There is often serious discrepancy between use in laboratory environment and on site. The paper identifies important aspects to be considered and shows ways to transfer innovations onto practical use.
