Abstract
An optical fibre sensing system () with an incident light source (), a wavelength spectrum interrogator (), and an optical fibre () with a substantially continuous fibre Bragg grating (). An upstream portion () of the optical fibre has an attenuation length to light to the interrogator () at a first equilibrium wavelength. A downstream portion () of the optical fibre reflects light to the interrogator () when a change in temperature and/or strain at the downstream portion () causes a portion of the fibre Bragg grating to reflect light to the interrogator () at a second wavelength and at a second intensity. A processor () is configured to analyse the reflected spectrum () to determine when a portion of the fibre Bragg grating () is experiencing a change in temperature and/or strain based on deviation in the reflected spectrum () from an initial peak corresponding to the initial wavelength.
