Paper Abstract

Fiber loop ringdown (FLRD), a uniform time-domain sensing scheme, has potential to help address the three key issues: Power losses, light intensity fluctuations, and high terminal equipment costs, in the development of fiber optic sensor networks for simultaneously sensing multiple quantities, including pressure, temperature, strain, chemical species, etc. with fast response, high sensitivity, and significantly reduced costs. Performance and design of a cluster of individual FLRD-based fiber optic sensors are presented. Multiplexing those individual FLRD sensor units into a large scale sensor system for multi-function sensing is proposed. System configuration, operation, and advantages are discussed.
