Novel system to interrogate distributed fiber strain sensors and pointtemperature sensors based on pulse correlation and FBGs

摘要

We are going to present and demonstrated the feasibility of a novel sensor interrogation scheme that combines the advantages of the distributed and point sensor systems using a robust interrogation technique. The experimental results show the high linearity and stability of the measurements. Also, our proposed scheme uses a tunable source with optical elements that have very few losses. Thus, the number of sensors that can be allocated in one fiber is very high.
