Paper Abstract
A novel spread spectrum technique is reported for passive multiplexing of interferometric optical fiber sensors. The technique relies on digital spread spectrum modulation of an optical source, and the use of correlation techniques to distinguish signals arriving from specified sensors in the network. The unique feature of the system is that correlation is achieved by the use of an integrated optic modulator, prior to optical detection. Pre-detection correlation exploits the high bandwidth of integrated optic devices, and enables the use of low bandwidth photodetectors and other (electrical) post-detection components.
