Miniaturized components with increasingly smaller geometric features are manufactured for electronics, medical engineering, communications engineering, and the motor vehicle industries to enable complex functions requiring only a minimum amount of space. Inspections of bore diameters smaller than 0.1 mm and slot widths of less than 10 µm are now routine measuring tasks. One typical example of this is the measurement of the geometry of nozzles in fuel injection systems for diesel engines using image processing sensors and the Werth Fiber Probe. The component to be measured is positioned in the measuring volume to an accuracy of one micrometer on a two-axis articulating holder. The tiny (approximately 0.1 mm) bores are “captured” by the image processing system. The actual measurement of the bore is then performed by the fiber probe. This determines both the shape and the spatial position of the bore holes (Fig. 64).
