PCT No. PCT/DE95/00036 Sec. 371 Date Jul. 17, 1996 Sec. 102(e) Date Jul. 17, 1996 PCT Filed Jan. 12, 1995 PCT Pub. No. WO95/19542 PCT Pub. Date Jul. 20, 1995An apparatus and a method are presented in order to carry out an automatic optical inspection of an off-center rotating component to be measured. Using a measurement procedure which avoids mechanical contact having a source producing parallel rays and a detecting means, the off-center rotating component is rotated about a rotational axis, whereby a motion of the detecting means is synchronized with the rotation and is carried out in such a fashion that the separation, in the direction of an optical axis, between the off-center rotating component and the detecting means remains constant. In this manner optical distortions are avoided which would otherwise occur in the optical measurement procedure.
