Time-division-multiplexed interrogation of fibre Bragg grating sensors using laser diodes

By A. Wilson, Stephen W. James and Ralph P. Tatam


An intensity-based technique for the interrogation of fibre Bragg grating sensors is described. The technique utilizes two longitudinal modes of a single, pulsed laser diode as a dual-wavelength source for grating illumination. Time-division-multiplexed addressing of sensor arrays in serial and tree topologies is also demonstrated
