  • Structured illumination with optimized illumination geometry
    Patent number: 11397312
    Abstract: An object transfer function for a sample object is determined on the basis of a reference measurement. Subsequently, an optimization is carried out in order to find an optimized illumination geometry on the basis of the object transfer function and an optical transfer function for an optical unit.

  • Autofocus with an angle-variable illumination
    Patent number: 10955653
    Abstract: Various aspects of the invention relate to techniques to facilitate autofocus techniques for a test object by means of an angle-variable illumination. Here, image datasets are captured at a multiplicity of angle-variable illumination geometries. The captured image datsets are evaluated in order to determine the Z-position.
