<p>The short-term and long-term waviness of a smooth surface (2) is determined quantitatively by means of a method which impinges light radiation (4) onto the surface (2), detects the resultant light image (22), and mathematically processes that image (22). The method permits a fast, non-contact evaluation of a smooth surface (2) with good correlation between the calculated values and the visual observation.</p> |
