Demultiplexing of fibre Bragg grating temperature and strain sensors
We describe a demultiplexing scheme for fibre optic Brag grating sensors in which signal recovery is achieved by locking each sensor grating to a corresponding receiver grating. As a demonstration, the technique is applied to strain and temperature sensing, achieving a resolution of 3.0 µε and 0.2°C...
