Example of the interference profile frequency filtering in order to eliminate the fringes. (a) Calculated profile before (dashed) and after (solid) third-order Butterworth filtering. (b) Frequency spectrum (Fourier transform) of the initial profile allows calculation of the filter's higher fh and lower fl frequencies on the basis of the fundamental frequency ff.
