An absolute distance measuring method and device including a transmission unit having a laser array comprising multiple measurement laser emitters arranged along a laser array axis and a receiver unit having at least one receiver array comprising multiple measurement receivers arranged along a receiver array axis for measuring of an absolute distance based on a respective detected transmission beam and the principle of time-of-flight. The laser array comprises at least a first reference laser emitter and the receiver array comprises at least a first reference receiver. The reference laser emitter and reference receiver define an internal absolute distance reference beam path for calibration of the device with respect to said measuring of absolute distance.

Multi-beam measuring device

A surveying device including a base defining a base axis (A), a support structure defining a rotation axis (B), a light emitting unit, a light receiving unit detecting reflected measuring light, and a rotation unit including a rotation body including at least one scanning mirror arranged tilted relative to the rotation axis (B) and a curved deflecting element different from the scanning surface. The surveying device also includes an imaging unit including a camera sensor which is fixedly arranged so that an optical axis of the camera sensor is directed towards the rotation body, such that only in a predetermined imaging-alignment of the rotation body around the rotation axis (B) the optical axis of the at least one camera sensor is deflected by the curved deflecting element by a desired angle and direction so that the field of view comprises a defined field angle around the rotation axis (B).

Surveying instrument for scanning an object and image acquistion of the object

The invention relates to a positioning apparatus, comprising a rotatable spindle, a sliding member, wherein a spindle counter segment of the sliding member is displaced along the spindle when the spindle rotates, a first guide for the sliding member, which interacts with a first guide counter segment of the sliding member and, in the process, leaves the sliding member with a linear mobility along the first guide axis and a pivotability about the first guide axis, and a second guide for the sliding member, which interacts with a second guide counter segment of the sliding member and, in the process, restricts the pivotability of the sliding member about the first guide axis.
