    摘要: An apparatus for and a method of evaluating a multilayer thin film of the present invention. An interference light beam in a predetermined wave number region is projected as a parallel beam onto a multilayer thin film sample and the interference light beam reflected by the sample is detected to find an interferogram. The interferogram is subject to Fourier transform, filtering and reverse Fourier transform so that a spatialgram is provided. Thereby the variation in incident angle of the light beam incident on the sample and in incident surface is reduced, and the spatialgram can be provided with accurate information of the multilayer thin film.
