METHOD AND DEVICE FOR DETECTING NICKEL SULPHIDE INCLUSIONS IN A GLASS PLATE

In a method for detecting nickel sulphide inclusions in a glass plate, in a detection step at least one recording of at least one region of the glass plate is made with an optical image recording device and positions of possible inclusions are automatically determined on the basis of at least one predetermined first criterion, in a depth-determining step a depth of the possible inclusion in the glass plate is determined and in a subsequent evaluation step an optical recording focused at the determined depth is evaluated on the basis of at least one predetermined second criterion, in order to detect from the possible inclusion a nickel sulphide inclusion.
