Time-Domain Addressing Technique for a Single-Channel Output and High-ResolutionFiber Bragg Grating Sensor System
A technique of time domain addressing is introduced to interrogate a four element fiber Bragg grating sensor array. The sensor elements with different fiber delays were illumined with a pulsed broad band source. Demodulation was achieved with an unbalance Michelson scanning interferometer. The single channel output sensor system, which is with a sensing resolution of 6 nε, was demonstrated with a sensitivity of 1.63°/με.
