Demultiplexing Of Fiber Bragg Grating Temperature And Strain Sensors

By G.P. Brady, S. Hope, Antonio B. Lobo Ribeiro, David J. Webb, Laurence Reekie, J.L. Archambault and David A. Jackson


We describe a demultiplexing scheme for fibre optic Bragg 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 mu epsilon and 0.2 degrees C, respectively
