fringe signal according to Figure2.1b, as well as that of the fringe signal
according to Figure2.6. Comparing the distribution of the spectra, it is
evident that the noise has an eect on the whole spectrum of the sig-
nal, and it is dicult to lter out such a noise spectrum in the frequency
domain.
2.3 PHASE DEMODULATION BASED ON
WINDOWED FOURIER TRANSFORM
WFT is an important method for nonstationary signal analysis. To over-
come the deciency of FT with poor localization in the spatial frequency
domains, Dennis Gabor adapted the FT in 1946 to analyze only a local
section of the signal at a time and p ...
