Influence of Sampling on Fourier-Transform Propfilometry
The phase error caused by sampling the fringe patterns in practical Fourier-transform profilometry is discussed. Another kind of spectrum overlapping is analysed that is caused by the discrete Fourier-transform (DFT). The criterion for the selection of sampling frequency is derived. The computer simulations and experiments verified the theories.
