1. A device, which comprises:
- a first emission beam path, which extends from a pulsed first light source via a scanner to surroundings of the device,a reception beam path, which extends from the surroundings via the scanner to a detector, andat least one second emission beam, which extends from at least one pulsed second light source and not via the scanner to the surroundings,a controller, which is configured to activate the pulsed first light source to emit a first light pulse along the first emission beam path, and to activate the at least one pulsed second light source, to emit a second light pulse along the at least one second emission beam path, andwherein the controller is furthermore configured to activate the detector to detect a reflection of the first light pulse along the reception beam path and to detect a reflection of the second light pulse along the reception beam path.

10. A method, which comprises:
-
activating a pulsed first light source to emit a first light pulse along a first emission beam path via a scanner into surroundings, activating a detector to detect a reflection of the first light pulse along a reception beam path, which extends from the surroundings via the scanner, activating at least one pulsed second light source to emit a second light pulse along at least one second emission beam path and not via the scanner into the surroundings, and activating the detector to detect a reflection of the second light pulse along the reception beam path.
