Abstract
A swept wavelength interrogation system includes a tunable light source for outputting a light beam that is tunable over a range of wavelengths and an optical reader head for distributing the light beam among a plurality of sensors and for measuring response spectra from the sensors. A wavelength-tracking device measures centroid wavelengths of the light beam. A processor calculates a centroid wavelength of the response spectra from the sensors based on the measured centroid wavelengths of the light beam.
