1. A swept wavelength interrogation system comprising:

  • a tunable light source having a light beam tunable over a range of wavelengths;

    an optical reader to distribute the light beam among a plurality of sensors and for measuring response spectra from the sensors; and

    a wavelength-tracking device to measure centroid wavelengths of the light beam with a given precision,the light beam having a linewidth that exceeds the given precision of the measured centroid wavelengths.
