More Information
Summary:A reflector arrangement for determining the position or marking of target points, having at least one retroreflector, and a beam detection unit, by means of which the orientation measurement radiation passing through the retroreflector is acquirable. The beam detection unit comprises a first sensor for generating a signal in dependence on an acquisition of orientation measurement radiation and a first beam guiding unit. The first sensor and the first beam guiding unit are arranged such that a detection field of view for acquiring the orientation measurement radiation is defined, an alignment of the detection field of view around the yaw axis is variable and orientation measurement radiation passing through the retroreflector is acquirable in dependence on the alignment of the detection field of view with the first sensor.
