The paper proposes the criteria for selecting the sampling condition in three-dimensional surface measurement. The criteria are based on the fact that there is a relationship between the correlation length of the measured surface and its high-frequency cut-off. Through the use of the sampled surfaces and the analytical models, it is shown that the criteria are equivalent to the power spectral analysis.
