摘要
以变形结构光场为研究对象，分析抽样对傅里叶变换轮廓术测量范围的影响，提出了实际测量中抽样频率选择的判断依据。
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.
