  • Patent number: 12196631
    Abstract: An optical fibre sensing system (300) with an incident light source (309), a wavelength spectrum interrogator (313), and an optical fibre (302) with a substantially continuous fibre Bragg grating (306). An upstream portion (318) of the optical fibre has an attenuation length to light to the interrogator (313) at a first equilibrium wavelength. A downstream portion (322) of the optical fibre reflects light to the interrogator (313) when a change in temperature and/or strain at the downstream portion (322) causes a portion of the fibre Bragg grating to reflect light to the interrogator (313) at a second wavelength and at a second intensity. A processor (315) is configured to analyse the reflected spectrum (314) to determine when a portion of the fibre Bragg grating (306) is experiencing a change in temperature and/or strain based on deviation in the reflected spectrum (314) from an initial peak corresponding to the initial wavelength.
