| 摘要 |
The invention relates to a method and an arrangement for determining the geometry of objects using a coordinate measuring device. An optical system (10) is used to form an image of at least one light or scanning spot whose position depends on the geometry of the object on at least one detector (30). The imaging scale, depth of field and distance from the object are adjusted by means of a zoom lens (18) whose lens groups (20, 22) are each power driven and are axially displaceable.
