APPARATUS FOR INTERROGATING FIBRE BRAGG GRATINGS |
摘要 |
Apparatus for interrogating an optical fibre comprising a plurality of fibre Bragg gratings each having a resonant wavelength in a different discrete wavelength band. The apparatus comprises a delay arrangement interposed in use in an optical path for light supplied to and/or reflected from the fibre Bragg gratings. The delay arrangement is configured to apply a different time delay to light in each of the discrete wavelength bands, whereby the light reflected from each of the fibre Bragg gratings is received at an interrogator port of the apparatus in a different discrete time interval.
