Demodulation Method of F-P Sensor Based on Wavelet Transform and Polarization Low Coherence Interferometry

Demodulation Method of F-P Sensor Based on Wavelet Transform and Polarization Low Coherence Interferometry

Polarized low-coherence interferometry (PLCI) is widely used for the demodulation of Fabry–Perot (F-P) sensors. To avoid the influence of noise and dispersion on interference fringes, this paper proposes a data processing method in which the wavelet tools are applied to extract useful information fr...
