Abstract:
A laser scanner for detecting spatial surroundings comprises a stator (21), a rotor (1), mounted on the stator (21) to be rotatable about a first rotational axis, and a rotary body (2), mounted on the rotor (1) to be rotatable about a second rotational axis. A laser source (6) and a detector (7) are arranged in the rotor (1). One optical link (9) each is configured on the second rotational axis on every side of the rotary body (2) between the rotor (1) and the rotary body (2) so that emission light can be introduced by the laser source into the rotary body (2) via the first optical link (8) and reception light can be discharge from the rotary body (2) via the second optical link (9). A first rotary drive (25) drives the rotor (21) and a second rotary drive (26) drives the rotary body (2). Two goniometers (4) and evaluation electronics (5) which are connected to the laser source (6) and the detector (7) allow association of a detected distance with a corresponding direction. The rotary body (2) can have a very compact design, is completely passive and therefore does not require any power supply or transmission of signals.
