  • Method and apparatus for determining a defocusing valve and for image-based determination of a dimensional size
    Patent number: 10719915
    Abstract: The invention relates to an apparatus and a method for determining a defocussing value (?z, ?z1, ?z2) for at least one image feature in an image, wherein at least one monochromatic image of an object is generated, wherein the defocussing value (?z, ?z1, ?z2) is determined on the basis of the image and depending on the wavelength (?) of the monochromatic image, and a method and apparatus for image-based determination of a dimensional size.
    Type: Grant
