Abstract

We propose and numerically demonstrate a novel technique for estimating the spectral content of the perturbation on a Fiber Bragg grating (FBG) sensor. The system utilizes an FBG array as a wavelength reference for time-stamping the wavelength shift of the sensor. This technique has demonstrated a good agreement between the actual and estimated spectrum. In addition to having the advantage of selecting the operational window of the sensor, it also gives an absolute measurement of the perturbation.
