Simple multiplexing scheme for fibre optic grating sensor network
Optics Letters, 18, (4), . (doi:10.1364/OL.18.001192).
A new approach for the interrogation of a large number of fiber-optic grating sensors is proposed and demonstrated for a small number of sensors in which signal recovery is achieved by matching a receiving grating to its corresponding sensor. This technique is demonstrated for both quasi-static and periodic measurands, and the resolution achieved for a single sensor-receiving grating pair for quasi-static strain of 4.12µ.epsilon.
