Fourier profilometry : ウィキペディア英語版
Fourier profilometry
Fourier profilometry is a method for measuring profiles using distortions in periodic patterns. The method uses Fourier analysis (a 2-dimensional Fast Fourier transform) to determine localized slopes on a curving surface.
This allows a ''x'', ''y'', ''z'' coordinate system of the surface to be generated from a single image which has been overlaid with the distortion pattern.
It is used specifically in measuring the shape of the human cornea for use in contact lens design.
