Abstract:
1. A method for producing an image of a layer of an object by imaging through a wide field optical element onto a resolving detector, comprising: illuminating the object in a focused manner on at least one object plane using at least two binary illuminating patterns wherein the illuminating patterns respectively comprise dark areas and light areas and the light areas or the dark areas or both the light areas and dark areas completely cover the object when the illuminating patterns are superimposed; detecting corresponding images for each illuminating pattern; and determining a layer image from the detected images, said layer image comprising partial segments that respectively reproduce a partial area of the object, the partial area having partial area edges and the partial area being arranged inside the light area of at least one of the used illuminating patterns, such that said partial area edges are arranged at a distance from edges of the light area about at least one predefined minimum distance, and respectively determining the partial segments with at least partial artificial light correction using at least two images which are respectively detected for different illumination patterns in which the partial area corresponding to the respective partial segment is arranged completely inside the light area of a first different illuminating pattern or completely inside a dark area of a second of the different illuminating patterns.
