DEMODULATION AND DENOISING TECHNIQUES FOR A MULTIPLEXED FIBRE FIZEAU INTERFEROMETER AND FIBRE BRAGG GRATING SENSOR SYSTEM BASED ON WAVELET ANALYSIS
Wavelet analysis is applied extensively to a multiplexed fibre Fizeau interferometer and fibre Bragg grating sensor system. Specifically, the discrete wavelet transform is used to demodulate the multiplexed sensor signal simultaneously; and two wavelet denoising methods are used to reduce the noise present in the signal and measurands record. Experimental demonstration is performed through the simultaneous measurement of quasi-static strain and temperature.
