<p>The invention relates to a leveling apparatus for optically detecting a height difference relative to a leveling staff and includes an objective (22a), a two-dimensional detector (21), a mount (13) for rotating both said objective (22a) and said detector (21) about a fixed vertical axis (5) of the apparatus, and a processor. The detector (21) is arranged such that its rows are inclined to an image of a vertical axis of the object by an acute angle. The invention also relates to a method of detecting a height difference of an Apparatus relative to a leveling staff including imaging the leveling staff onto an array (21) of detectors such that the image of a vertical axis of the staff is inclined to detector rows at an acute angle.</p> |
