  • Method and device for analyzing the surface of a substrate
    Patent number: 7430049
    Abstract: A process for scanning a surface of a substrate, which process takes at least one reflected image of at least one test pattern on the surface and extracts by digital processing local phases in two directions. Variations in local slopes are calculated by digital processing from the local phases to deduce therefrom variations in curvature or variations in altitude of the surface.
    Type: Grant

  • Mewthod and device for analysing the surface of a substrate
    Publication number: 20060050284
    Abstract: The object of the invention is a process for scanning a surface of a substrate (2), which process consists in taking at least one reflected image of at least one test pattern (1) on the said surface and extracting by digital processing local phases in two directions, characterized in that variations in local slopes are calculated by digital processing from the local phases in order to deduce therefrom variations in curvature or variations in altitude of the said surface.
