The laser tracker may include a base defining a standing axis, a beam steering unit for emission of a measuring radiation and for receiving at least a part of the measuring radiation reflected by the target. The beam steering unit is motorized to be pivotable relative to the base around the standing axis and a tilt axis extending substantially orthogonal to the standing axis. Furthermore, the tracker has a distance measuring unit configured as an interferometer for determining a change in distance to the target by means of interferometry, an interferometer laser beam source for generating the measuring radiation for the interferometer and an angle measurement functionality for determining an alignment of the beam steering unit relative to the base. The interferometer laser beam source may be configured as a laser diode.

摘要： The invention is directed to a device for direct detection of the spatial position of a probe element in a multi-coordinate measuring apparatus, with a reference system comprised of at least one first standard and one second standard that are associated with coordinate axes of the measuring apparatus. The first standard is a planar standard with a line grating array. The second standard is non-contacting relative to the first standard and movable in two dimensions by means of a cross slide. Provision is made for a first position measuring system for determining the spatial position of the second standard with respect to the first standard, and for a second position measuring system for determining the spatial position of a carriage carrying a three-dimensional probe assembly, with respect to the second standard. The device forms in an associated multi-coordinate measuring apparatus a continuous measuring chain from the first standard to the tip of the probe element. This supplies directly a measurement result considering any guide inaccuracies, without the need to perform any path corrections.
