Abstract: A method includes comparing a received beam hitting a laser receiver in a transverse arrangement with a rotating laser beam which is moved about an axis of rotation in a vertical position by a rotary laser. The laser receiver includes an evaluating unit and a detection field having a longitudinal direction and a transverse direction. The rotary laser is arranged on a rotational platform that can be adjusted about a rotation axis, and the vertical laser plane that the rotating laser beam produces is moved by the rotational platform in a direction of rotation about the rotation axis. In the longitudinal direction of the detection field, an adjustment direction of the received beam relative to the laser receiver is determined by the evaluating unit and the adjustment direction of the received beam is compared with the direction of rotation of the rotational platform by the evaluating unit.

Abstract: A method for comparing a reception beam incident on a laser receiver with a rotating laser beam transmitted by a rotating laser in a direction of rotation, where the laser receiver includes an evaluation unit and a detection field having a first measuring range and a second measuring area, includes, when the reception beam is incident on the detection field, determining a first reception signal which represents a first time trend of the incident reception beam in the first measuring range and a second reception signal which represents a second time trend of the incident reception beam in the second measuring range. A direction of movement of the reception beam relative to the laser receiver from the first and the second reception signals is determined. The direction of the movement of the reception beam is compared by the evaluation unit with the direction of rotation of the rotating laser beam.

Abstract: The invention relates to a method for comparing a received beam (24) hitting a laser receiver (12) in a transverse arrangement with a rotating laser beam (22), which is moved about an axis of rotation (21) in a vertical position by a rotary laser (11), wherein the laser receiver (12) comprises an evaluating unit and at least cuie detection field (25) having a longitudinal direction (28) and a transverse direction (29). The rotary laser (11) is arranged on a rotational platform (14) that can be adjusted about a rotation axis (15), and the vertical laser plane that the rotating laser beam (22) produces is moved by the rotational platform (14) in a direction of rotation (16) about the rotation axis (15).

Abstract: The invention relates to a method for comparing a receive beam (24) incident on a laser receiver (12) with a rotating laser beam (22), which is transmitted by a rotating laser (11) in a direction of rotation (23) about an axis of rotation (21), wherein the laser receiver (12) comprises an evaluation unit and at least one detection field (25) having a first measurement area and a second measurement area. When the receive beam (24) is incident on the at least one detection field (25) of the laser receiver (12), the evaluation unit determines a first receive signal, which represents the time progression of the incident receive beam (24) in the first measurement area, and a second receive signal, which represents the time progression of the incident receive beam (24) in the second measurement area.

Abstract: Method for comparing a received beam (24) incident on a laser receiver (12) in a longitudinal arrangement with a rotating laser beam (22), which is moved by a rotating laser (11) in a horizontal position about an axis of rotation (21), wherein the laser receiver (12) comprises an evaluation unit and at least one detection field (25) having a longitudinal direction (28) and a transverse direction (29). The rotating laser (11) is arranged on a tripod (14) adjustable along an axis (15) and the horizontal laser plane that the rotating laser beam (22) produces is moved by the tripod (14) in a height direction (16) along the axis (15). In the longitudinal direction (28) of the detection field (25), the evaluation unit determines an adjustment direction of the received beam (24) relative to the laser receiver (12), and the evaluation unit compares the adjustment direction of the received beam (24) with the height direction (16) of the tripod (14).
