Abstract

A method for reproducibly determining object characteristics is disclosed. Herein an object is imaged onto a detector by means of an imaging optics and detected thereon. A correction function k is applied to a brightness measuring result N originally detected by a detector in such a way, that a corrected brightness measuring result N′ is proportional to a brightness I impinging on the detector.
