Abstract : An apparatus for the determination of the wavelength and the detection of wavelength shifts in wavelength-encoded fiber sensors, such as Bragg grating sensors. The apparatus is implemented in fiber and uses a pair of tuned fiber gratings to provide a filter type function that tracks the wavelength component of a signal from a wavelength-encoded sensor.
