Paper Abstract

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 measured strain slightly differs from the farfield strain. However, the sensors used in this study were insensitive to the disturbance.
