Paper Abstract

A novel wavelength detection and demodulation technique of fiber Bragg gratings sensors is put forward. The principle, experimental setup and results of the sensor are analyzed. The new technique converts detections of shift of center reflecting wavelength into detection of light intensity extremum. Furthermore, a spatial division multiplexing system of Bragg gratings sensors based on the novel technique is developed. The multiplexing numbers are not confined by bandwidth of light source and tunable scope of single fiber Bragg grating.
