Title: METHOD FOR COMPARING A RECEIVED BEAM HITTING A LASER RECEIVER WITH A ROTATING LASER BEAM
Abstract:
The invention relates to a method for comparing a received beam (24) hitting a laser receiver (12) in a longitudinal arrangement with a rotating laser beam (22), which is moved about an axis of rotation (21) in a horizontal position by a rotary laser (11), wherein the laser receiver (12) comprises an evaluating unit and at least one detection field (25) having a longitudinal direction (28) and a transverse direction (29). The rotary laser (11) is arranged on a stand (14) that can be adjusted along an axis (15), and the horizontal laser plane that the rotating laser beam (22) produces is moved by the stand (14) in a height direction (16) along the axis (15). In the longitudinal direction (28) of the detection field (25), an adjustment direction of the received beam (24) relative to the laser receiver (12) is determined by the evaluating unit, and the adjustment direction of the received beam (24) is compared with the height direction (16) of the stand (14) by the evaluating unit.
