ABSTRACT:
A method measures a nolinearity profile of a sample with at least one sample surface and having a sample nonlinearity profile along a sample line through a predetermined point on the sample surface. The sample line is oriented perpendicularly to the sample surface. The method includes measuring a Fourier transform of the sample nonlinearity profile and obtaining a reference nonlinearity profile from a reference material. The method includes forming a first composite sample having a first composite nonlinearity profile and forming a second composite sample having a second composite nonlinearity profile inequivalent to the first composite nonlinearity profile. The method further includes measuring a Fourier transform of the first composite nonlinearity profile and measuring a Fourier transform of the second composite nonlinearity profile. The method further includes calculating the sample nonlinearity profile using the Fourier transforms of the sample nonlinearity profile, the reference nonlinearity profile, the first composite nonlinearity profile, and the second composite nonlinearity profile.
