Abstract
The invention relates to a method for adjusting an optical rotating data transmission device having two units that are rotatable with respect to each other about a rotation axis, and that each have a coaxial collimator for coupling light in or out, and relates also to an optical rotating data transmission device that is adjustable by means of the method. For an adjustment, a deviation of a light beam from the rotation axis is determined by means of two detectors at different distances, and from this a positional deviation and also a tilt of the light beam is calculated and suitably compensated.
