Abstract

A novel technique for multiplexing interferometric optical fibre sensors has been developed . The technique uses spread spectrum modulation of a semiconductor laser and electronic correlation detection of the returned signals from a network of interferometric sensors . A network consisting of two interferometric sensors in parallel has been assembled to investigate performance parameters such as cross-talk , and initial results from our experiments are reported.
