Abstract:
1. A coordinate measuring device, comprising: a carrier which can be rotated about at least two axes relative to a base, the carrier being automatically alignable with a spatially mobile measuring aid by means of a closed loop control arrangement by rotation about these at least two axes, wherein the coordinate measuring device comprises: at least one optical distance measuring apparatus for measuring the distance to a spatially mobile measuring aid; at least one light source for emitting light directly or via optical elements, this light being visible as a target point when reflected by the measuring aid; at least one target detection unit for determining a position as the position of an image of the target point on a position detection sensor; the closed loop control arrangement being adapted to align the carrier with the measuring aid by rotation about the at least two axes of the carrier according to a fine position and a coarse position; and the light source being a superluminescent diode (SLED) and wherein at least one set of exit and/or entry optics of the at least one optical distance measuring apparatus, the at least one light source, the at least one target detection unit, the closed loop control arrangement and the light source are arranged so that said optics can be moved together on the carrier.
