An method for determining a surface profile of an object is described. The method typically includes providing a surface profile (e.g., a height profile) of a test object measured by an interferometric profiler. Information related to field- and object orientation-dependent systematic errors of the interferometric profiler is provided. The surface profile is corrected based on the field- and orientation-dependent errors. Also described is a method for determining the field- and orientation dependent errors of a profiler.
