Abstract:
1. An arrangement for detecting coatings that are arranged on surfaces of structural components parts and for determining the chemical characteristics and surface properties of these coatings, comprising: a light source for illuminating a coating to be analyzed on the surface of the structural component part; optical elements for imaging the light source on an entrance slit over the surface of the coating to be analyzed; a grating which images light from the entrance slit on a two-dimensional detector unit in a wavelength-dependent manner; and an evaluating unit being electrically connected to the detector unit for evaluating and processing signals supplied by irradiated detector elements of the detector unit, the evaluating unit being arranged to determine measurement values for the roughness of the surface of the analyzed coating from the breadth of the irradiated area on the detector unit.
