Abstract
A compact all-fiber interrogation technique for Bragg sensors is presented. It is based on the generation of an electric carrier by modulating the cou pling length of a wavelength-division multiplexer (WDM), Theoretical and ex perimental results are presented when both serrodyne and sinusoidal modulat ions are considered. It is shown that this technique provides static micros train resolution in measurement intervals larger than some millistrain.
