Abstract
In recent years a strong interest has developed in embedded fiber optic sensors for the monitoring of strain, temperature, and other parameters in structural materials [1]. The fiber Fabry-Perot interferometer (FFPI) using internal mirrors [2-4] is a strong candidate for this application because it provides localized ("point") sensing capability and high sensitivity, and is amenable to time-division multiplexing. Here, new results on the embedding of FFPIs in metals and composites are reported.
