The invention relates to a device for determining the position of a first shaft () and of a second shaft () that is joined to the first shaft by means of a coupling (), with respect to each other, having a first measurement unit being placed on a circumferential surface of the first shaft and a second measurement unit being placed on a circumferential surface of the second shaft, wherein at least one of the two measurement units has means () for producing at least one light beam bundle () and at least one of the two measurement units has detection means () in order to detect the impingement position of the light beam bundle on at least one detection area ().

A method for measuring flatness of a factory floor upon which machinery is to be mounted using a rotating laser beam that emits a rotating laser beam in an essentially horizontally plane. A photosensitive position sensor delivers an electrical pulse, which is identified by its timing and phase angle, during illumination by the laser beam. The phase angle and timing of these pulses constitute a measure of the position of the sensor in the coordinate system. Measurements are taken with the sensor positioned at each location at which the machinery is to be fixed to a factory floor. The method determines any differences in height between the measurement points and the amount, if any, that the floor needs to be adjusted at each mounting point to insure that a machine that is affixed to the floor these points will be level.

The spatial position of rollers or other mutually adjacent articles is measured or examined by indirect transport of a reference direction. To this end, an adaptor is placed on one of the rollers. The adaptor is equipped with a light source which emits a light beam substantially parallel to the axis of rotation of a roller. The light beam is sensed by a movable sensor unit. The latter determines, at the same time, the angle of incidence of the light beam according to two axes, relative to the sensor unit, and the orientation of the sensor unit relative to a reference axis system (laboratory system). A multi-axially operating gyroscope is used for the last-mentioned measurement. A suitably programmed electronic system or computer determines, from the two measured values, the orientation of the adaptor and of the roller with respect to azimuth and elevation in the laboratory system. The measured values which are determined can be utilized for the purpose of making a comparison with the corresponding values of further rollers or articles, so that an apparatus for parallelism measurements which is easy to handle is provided.
