Abstract
An interrogator for a plurality of sensor fiber optic gratings. The interrogator includes an optical source for providing signals to the plurality of sensor fiber optic gratings. At least one optical filter converts optical signals, returned from the plurality of sensor fiber optic gratings, from (a) changes in peak reflection wavelength to (b) changes in intensity. At least one optical receiver receives the converted optical signals from the at least one optical filter.
