Measurement system based on a time-of-flight technique and Fabry-Perot optical fiber sensors have been used to determine the strain state in the composite structure. In theory the optical fiber causes a local disturbation to the structure such that m

The monitoring of fuel tanks and toxic liquid containers with embedded long optical fibers makes it possible to determine their condition and to detect probable environmental risks. We present here measurements of microbending loss in long, single-mo
