Keywords : thin films * Michelson's interferometer * interference fringes * interference pattern video-record * computer procesed video-signal * fast Fourier transformation
Subject RIV: BH - Optics, Masers, Lasers

This measurement is realized by Michelson's interferometer. The video-signals from two rows of the intensity distribution from the part with and without a layer are numerically filtered via fast Fourier transformation and the phase change of the two periodical "continous" functions is evaluated by the first and second derivatives.
