Abstract

Using WDM technology to solve the problem of the reuse addressing the fiber grating sensing network, the system USES a reference grating for temperature compensation, the reference grating was put in the same temperature field as the measuring grating array, but does not suffer the effect of strain, reference grating principle and method of signal processing and measurement of grating is completely consistent. Because of fiber Bragg grating strain and temperature response is linear, so there is no difference between both in terms of signal demodulation, directly from minus the reference grating demodulation measuring grating demodulation results as a result, thus realized the reference grating is used to compensate temperature disturbance to the influence of strain measurement. Using empirical mode decomposition (EMD) method for fiber Bragg grating sensor signal de-noising.
