Wyznaczenie ułamkowych rzędów izochrom metodą filtrowania monochromatycznego

The method presented in the paper enables to determine the isochromatic fringes of fractional order. To analyse the isochromatic patterns obtained by using of the wbite light the monochromatic filters have been appiied. The method was experimentally examined on the test specimen. The limit of application of the method bas been determined.
