Abstract:
1. A method for the quantitative determination of surface properties, wherein a spatially resolved image of a surface to be analysed, which contains a plurality of measured values, is evaluated, said method comprising the steps: analysing the measured values in order to determine those surface areas (A) of the image which represent a specific physical property that can be characterised by the measured values and determining a result value (I) of said physical property, wherein said result value is characteristic of the measured values of the physical property of all those surface areas (A) determined by analysing the measured values, on a processor; wherein the result value (I) is output against the size of the determined surface areas (A), wherein the size of the determined surface areas are obtained by determining the number of pixels represented by those determined surface areas having an intensity above a threshold value, and wherein for a selected plurality of spatially resolved images, the result value is plotted against the size of the determined surface areas (A) in a same diagram, and wherein in the diagram, orientation lines are indicated which symbolise different properties of the surface to be analysed.
