Method and rotative laser for determining a positional information of at least one object

摘要

Rotation laser(s) (2) with a rotation unit and a laser source is used for emitting laser radiation (5) in a rotating direction that contains angle-dependent information from which the emission direction can be derived so the emission direction can be combined with the direction from the laser to the object (1) receiving it. The laser radiation is emitted and received at a first detector (6a) of the object and deriving a first emission direction of the received radiation from the angle-dependent information so the direction from the laser to the object can be determined. An independent claim is also included for a rotation laser for determining positional information of at least one object.
