Paper Abstract
Two novel techniques for multiplexing interferometric optical fiber sensors have been developed. The techniques use spread spectrum modulation of a semiconductor laser and electronic or electro-optic correlation detection of the returned signals from a network of interferometric sensors. A network consisting of two interferometric sensors in parallel has been assembled. Initial results from our experiments show that while the interrogation system monitors a specific sensor, the signals from other sensors in the network can be suppressed by over 25 dB.
