Question

The 2D Fourier transform (2D FT) is a useful tool when dealing with surface analysis. Select all the correct statements.

Accepted Answer

Patterns separated by larger distances in the Fourier domain correspond to lower frequencies in the spatial domain.

Accepted Answer

The 2D FT is useful for detecting surface defects.

Answer

The 2D FT transforms every spatial frequencies into lines in the Fourier domain.

Answer

The 2D FT provides spatial information about where specific surface features are located.

Answer

Changing the orientation of a surface does not affect its 2D FT.
