Abstract:

The invention pertains to a system and method for providing accurate measurements of the reflected wavelengths from multiple strings of fiber Bragg grating FBG elements using a single scanning optical filter and an isolated duplicate reference string of FBG elements. A reference string of FBG elements permits precise long-term wavelength determination of sensors by providing real-time adaptive calibration adjustments to correct for any nonlinearities in the response of the single scanning optical filter.
