Abstract
The present invention relates to an optical fiber sensor, comprising an optical fiber having embedded therein at least one fiber core () extending along a length of the optical fiber, the at least one fiber core having a plurality of single fiber Bragg gratings () arranged in series along the at least one fiber core (), wherein each fiber Bragg grating () has a single reflection spectrum around a single reflection peak wavelength when interrogated with light in an untrained state of the at least one fiber core (), wherein the reflection peak wavelengths of the single reflection spectra are different from fiber Bragg grating () to fiber Bragg grating () along the at least one fiber core. Also described is an optical system and a method of interrogating an optical fiber sensor.
