Abstract:
1. A laser scanner comprising: a stator; a rotor mounted on the stator so as to be rotatable about a first axis of rotation; a rotary body mounted on the rotor so as to be rotatable about a second axis of rotation and having a passage boundary parallel to the second axis of rotation for the passage of transmitted light and received light; evaluation electronics; a laser source; a laser light detector, a first rotary drive making the rotor driveable; and a second rotary drive making the rotary body driveable, the spatial orientation of the rotary body being detectable via two angle-measuring devices and the evaluation electronics being connected to the laser source, the detector and the angle-measuring devices being configured in order to coordinate a detected distance with a corresponding orientation, wherein the laser source and the detector are arranged in the rotor and one optical link each having in each case first and second optical transmission elements rotationally decoupled from one another is formed between rotor and rotary body on the second axis of rotation on both sides of the rotary body, the rotary body being configured to couple transmitted light into the rotary body via the first optical link and to couple received light out of the rotary body via the second optical link, and the first optical transmission element being coordinated with the rotary body and the second optical transmission element being coordinated with the rotor.
