摘要
A method for determining roughness data and/or topography data of surfaces in material microscopy, particularly from flat samples, based on a shearing polarization interferometrical sequence with a microscopic “TIC” module (“Total Interference Contrast Module”) of a microscope, wherein the method can be carried out both polychromatically and monochromatically. At least two tilted wave fronts are generated, which after reflection or transmission on a sample generate two images of said sample in the form of fringe patterns, said images being offset relative to one another and interfering with one another, from which roughness values and height topographies of the surface of the sample are determined by application of image evaluation.
