Abstract
A combined spatial- and time-division-multiplexing topology with drift-compensated high-resolution wavelength-shift detection is reported for fiber Bragg grating sensors. An eight-element grating sensor array is demonstrated based on this topology. A resolution of ~1.2 με over a range of ~1.5 mε with a measurement bandwidth of 30 Hz (~0.22 μɛ/Hz−−−√) has been achieved for quasi-static strain measurement.
