Abstract

We describe the design and performance of a prototype fiber Bragg grating demodulation system based on the use of a scanning fiber Fabry-Perot filter. The computer driven system is capable of demodulating several arrays of wavelength division multiplexed gratings at various scanning rates for real-time strain display and data logging. The instrument represents a new measurement tool which should be useful in a variety of structural health monitoring applications. Results obtained by the system in several applications are presented and system performance limitations are discussed.
