Abstract: A laser scanner and a system with a laser scanner for measuring an environment. The laser scanner includes an optical distance measuring device, a support, a beam steering unit rotatably fixed to the support which rotates around a beam axis of rotation. The beam steering unit includes a mirrored surface which deflects radiation used in the optical distance measurement and an angle encoder for recording angle data. The optical distance measurement is performed by a progressive rotation of the beam steering unit about the beam axis of rotation and the continuous emission of a distance measurement radiation, the emission being made through an outlet area arranged in the direction of the mirrored surface on the support, the receiving optics for receiving radiation are 10 arranged on the support, and wherein the outlet area has a lateral offset with respect to the optical axis of the receiving optics.

Abstract: The invention relates to a reality capture device for generating a digital three-dimensional representation of an environment, particularly for surveying or monitoring an infrastructure. The reality capture device comprises a laser scanner and a housing enclosing an internal space, which has a first and a second climate zone. The reality capture device has a common air circulation element to provide active air circulation through an air guiding arrangement, wherein the air guiding arrangement is configured in such a way that different air flow characteristics of the active air circulation are achieved with respect to different regions associated with cooling of the two different climate zones. The first climate zone is configured to be free of active air circulation and the second climate zone is configured to have active air circulation for directing air to the inside part of a corresponding heat dissipation element.
