Abstract
Some embodiments of the invention include a coordinate measuring machine for detecting the position and alignment of a spatially movable measuring aid. The coordinate measuring machine may include a retroreflector; a base; a support, which is fixed on the base rotatably about a first rotation axis; a beam directing unit, which is fixed to the support rotatably about a second rotation axis substantially orthogonal to the first rotation axis; means for detecting a rotation angle of the support relative to the base; and means for detecting a rotation angle of the beam directing unit relative to the support. In some embodiments, the beam directing unit comprises a laser emission and reception optical unit and a first optical distance measuring unit having at least one first distance measuring device for measuring the distance to a retroreflector of the measuring aid by means of a first measurement radiation.
