Paper Abstract

The sensitivities of interferometer-based fiber optic sensors to both strain and temperature are compared. The first compact fiber optic strain rosette has been developed and its performance is compared with a conventional foil strain rosette when embedded within composite material. It is shown that an embedded Michelson fiber optic sensor can detect acoustic emission resulting from threshold delaminations within composite materials.
