Metrology

single-image 3D shape measurement that recovers height from the phase of a projected grating by filtering its Fourier spectrum.

In metrology, Fourier transform profilometry refers to single-image 3D shape measurement that recovers height from the phase of a projected grating by filtering its Fourier spectrum. This meaning comes from Takeda (1983) in Applied Optics.[1]
