Fourier profilometry
text:
Fourier profilometry is a method for measuring profiles using distortions in periodic patterns. The method uses Fourier analysis 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.
