摘要

The device (2) has a light source (12) that outputs a measuring ray (14) and another light source (16) for outputting a pilot ray (18). A dichroitic mirror is arranged such that the measuring ray and the pilot ray are emitted from the transmitter device in a collinear manner. A channel (32) is arranged in the receiver device for guiding the measuring ray and the pilot ray, and a tilted mirror is arranged in a housing. An independent claim is also included for a method for performing a scan of a measuring object.
