| Abstract: | 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. |

| Keywords: | sampling spectrum overlapping Fourier transform profilometry |
