Abstract

An embedded optical fiber was used to measure the strain in a composite laminate. Strain was deduced from the induced propagation delay as measured by radio-frequency optical interferometry. The output of the optical sensor was found to follow the actual integrated average strain with some fluctuations which are attributed to polarization effects.
