PCT No. PCT/EP91/00082 Sec. 371 Date Sep. 16, 1994 Sec. 102(e) Date Sep. 16, 1994 PCT Filed Mar. 21, 1990 PCT Pub. No. WO91/14922 PCT Pub. Date Oct. 3, 1991.A method is proposed for checking the alignment of body axes for parallelism, which method can be carried out in simple manner with low effort in auxiliary apparatus means and yet delivers highly accurate measurement results. In the method, a measurement beam L, preferably a laser beam, is emitted transversely to the body axis of each body 1 and 2 and on rotation about the body axis impinges on at least three detectors 4a, 4b, 4c, 4d and 4e in succession, which respectively deliver a signal denoting the position of the point of incidence along a detector axis 5 of the respective detector. From the detector signals and the relative position, which optionally is separately determined, of points of intersection of the body axes and the detector axes with a surface spanned by a measurement beam, the relative spatial position for each body axis with respect to a reference axis is computed. Also proposed is a particularly suitable device for carrying out the method.
