Abstract (EN): It is reported a new dynamic electrical interrogation technique based on the modulation of two Bragg gratings structures located in the readout unit that permits to attenuate the effect of the 1/f noise of the electronics in the resolution of the LPG-based curvature sensors. The new concept is tested to detect large variations of curvature being achieved a resolution of 6.56 × 10-3 meters.
