Abstract
A device and method for tracking a spectral response. The device and method including inputting light to a waveguide medium having a plurality of perturbation sensors disposed in a spaced relationship in the waveguide medium; receiving a plurality of signals reflected from the plurality of perturbation sensors; retrieving from the received signals, data representing a plurality of signal values, each signal value comprising at least a magnitude value and a wavelength value; identifying within the plurality of signal values, at least a first signal value and a second signal value, being in an overlap state; estimating, for at least some of the plurality of perturbation sensors, an expected signal value; associating each expected signal value with a respective signal value from the plurality of signal values; updating each expected signal value with the associated signal value.
