The disadvantage is that the reflection of the rotating laser beam on the reflective surface is not detected by the evaluation unit
[0007] The methods known from US 7,119,316 B2 and US 7,224,473 B2 for comparing the received radiation incident on the laser receiver with the rotating laser beam of the rotating laser have the disadvantage that the rotating laser beam is reflected Reflections on the surface are not detected by the evaluation unit of the laser receiver and will be incorrectly attributed to a rotating laser beam

Embodiment Construction

[0041] figure 1 A device 10 is shown with a rotation laser 11 and a laser receiver 12 , which are connectable via a communication link 13 . The communication link 13 is designed as a wireless communication link or as a wired communication link. The rotary laser 11 is arranged in a horizontal position for horizontal application of the rotary laser 11 and the laser receiver 12 is arranged in a longitudinally arranged configuration.

[0042] The rotating laser 11 is arranged on a motorized tripod 14 which enables automatic height adjustment of the rotating laser 11 along the axis 15 in the height direction 16 (double arrow). In addition, a rotary platform 17 is provided which enables an automatic angular adjustment of the rotary laser 11 about the axis of rotation 18 of the rotary platform 17 . The swivel platform 17 can be integrated into the tripod 14 or the swivel laser 11 or can be constructed as a separate component which is arranged on the tripod 14 . The rotation laser ...

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 measurementarea. 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 measurementarea. The evaluation unit determines a direction of movement of the receive beam (24) relative to the laser receiver (12) from the first and second receive signals, and the direction of movement of the receive beam (24) is compared by the evaluation unit with the direction of rotation (23) of the rotating laser beam (22).

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for comparing a received beam incident on a laser receiver with a rotating laser beam and a method according to the preamble of claim 9 Apparatus for implementing such methods. Background technique [0002] Rotating lasers are used indoors and outdoors for leveling and marking tasks, such as displaying horizontal, vertical or obliquely extending laser marks on target surfaces or determining and checking horizontal height extensions, vertical lines, concentric lines and plumb points. The rotating laser can be arranged in an instrument orientation (Geraetelage) configured in a horizontal position (Horizontalage) and a vertical position (Vertikallage). Here, a horizontally applicable rotary laser that is only used horizontally differs from a horizontally and vertically applicable rotary laser that is used horizontally and vertically. [0003] A maximum laser power is defined in rotat...
