TL;DR: In this article, a minimum variance shift technique for wavelength detection in fiber Bragg grating (FBG) sensors is proposed, which has been demonstrated to offer high detection accuracy even when the spectrum of the FBG is in partial overlap with a neighboring FBG within a wavelength division multiplexed sensor array.

TL;DR: In this paper, the use of a spectrum correlation technique for detecting Bragg wavelength shifts in fiber Bragg grating sensors has been reported, and experimental results show that the technique provides higher detection accuracy than the conventional peak detection technique.

TL;DR: An amplitude-division-multiplexed interferometric sensor array for locating acoustic emission and can be extended for two- and three-dimensional location of acoustic emissions by the addition of one or two more sensing arms in the interferometer.

TL;DR: In this paper, a novel current sensor based on a fiber Bragg grating (FBG) using a cantilever beam and a linear magnetic actuator is presented. And the change of current is transferred to the Bragg wavelength shift with good linearity and repeatability.

TL;DR: In this paper, an amplitude division multiplexed interferometric sensor array for locating acoustic emission is proposed, which is composed of three arms, the two sensing arms have different interference amplitude with the reference arm, so we can judge whether a sensor receives sound or not from the composite interference amplitude.
