Abstract

In an embodiment a method for position determination of an object in a spatial area is provided in which the object is illuminated with at least one light beam. The light beam does not cover the complete spatial area and is guided into a part of the spatial area in which the object is present depending on the position of the object. In another aspect a method for measuring a surface is provided.
