Paper Title:
Application of Wavelet Digital Filter of Fourier Transform Profilometry in 3-D Measurement
  Abstract

Fourier transform profilometry in 3-D measurement based on wavelet digital filter is presented in this paper. Before phase demodulation, original modulated grating image is handled with wavelet transform in order to remove the background components and high frequency. This method resolves spectrum overlapping at some extent and reduces the requirement of low-pass filter.
