Abstract
An object is illuminated sequentially using at least two illumination geometries. An intensity image of the object is captured for each one of the at least two illumination geometries. The intensity images are combined for producing a results image. Combining is carried out in such a way that the results image satisfies a predetermined optimization criterion. By way of example, the optimization criterion may relate to an image contrast, an edge steepness or an image sharpness. Optimization may be carried out with a spatial resolution.

A method for producing a results image of an object by means of an optical apparatus, wherein the method comprises:
- sequentially illuminating the object using at least two illumination geometries by means of an illumination apparatus of the optical apparatus,
- for each one of the at least two illumination geometries:
- capturing an intensity image of the object by means of a detector of the optical apparatus during illumination with the respective illumination geometry, and
- combining the intensity images for producing the results image by means of a computing unit,
- wherein combining is carried out in such a way that the results image satisfies a predetermined numerical optimization criterion, and
- further wherein combining is carried out with a spatial resolution for various regions of the intensity images such that the various regions of the results image satisfy the predetermined numerical optimization criterion.
An optical apparatus, configured to produce a results image of an object,
- wherein the optical apparatus comprises:
- an illumination apparatus configured to illuminate the object sequentially using at least two illumination geometries,
- a detector configured to capture an intensity image of the object for each one of the at least two illumination geometries during illumination with the respective illumination geometry, and
- a computing unit configured to combine the intensity images for the purposes of producing the results image,
- wherein the computing unit is configured to combine the intensity images in such a way that the results image satisfies a predetermined numerical optimization criterion, and
- further wherein the computing unit is configured to carry out the combining with a spatial resolution for various regions of the intensity images such that the various regions of the results image satisfy the predetermined numerical optimization criterion.
