Abstract
We present a new method for the interrogation of large arrays of Bragg grating sensors. Eight gratings operating between the wavelengths of 1533 and 1555 nm have been demultiplexed. An unbalanced Mach– Zehnder interferometer illuminated by a single low-coherence source provides a high-phase-resolution output for each sensor, the outputs of which are sequentially selected in wavelength by a tunable Fabry–Perot interferometer. The minimum detectable strain measured was 90 nɛ/Hz−−√at 7 Hz for a wavelength of 1535 nm.
