Abstract

We describe an active form of a frequency division matrix array network developed to support both interferometric sensors and fiber Bragg gratings to demodulate both quasistatic and periodic measurands., Novel telemetry allows an improved measurement range using a single source and uses a fundamental interferometric principle for self-calibration. High resolution is achieved through active but remote demodulation of passive sensors, A resolution of 0.019 mn with a measurement range of 62.8 mu m for an interferometric sensor and a strain resolution of 0.19 mu epsilon with a measurement range of 6.28 m epsilon was obtained for fiber Bragg grating sensors.
