Vorrichtung und Verfahren zur winkelaufgelösten Streulichmessung

The device has an illumination device to illuminate a sample (1) with light under an incident angle. A detector assembly detects two portions of light strewn having different light frequencies at sample. An evaluation unit evaluates output signals of detector assembly. The values for a power spectral density (PSD) are determined to analyze the scattered components and parameters for the connection of fractal spectral power density. An independent claim is included for an angle-dissolved scattered light measurement method.
