Abstract

A multichannel Bragg grating fiber laser demodulation system capable of interrogating four or more Bragg grating sensors for strain and temperature monitoring has been designed and developed. System configuration and various practical considerations for a field deployable system are discussed. Preliminary data indicates a dynamic strain range in excess of 5000 (mu) (epsilon) at a resolution of 1 (mu) (epsilon) . Both the strain dynamic range and resolution are easily modified.
