Abstract: An apparatus and method for finding part position relations of parts of mechanical and opto-mechanical machining and quality control systems, and for recognizing these parts, is disclosed. The present invention relies on optical contactless sensing technology, with recording of optical fiducial patterns and therefrom determining positions close to the work positions without physical contact. Part positions of machines are determined by associating or mechanically integrating fiducial patterns (1) with key parts, and optically detecting the images of these patterns. Part positions and displacements according to given part position finder (6) strategies are found, by associating fiducial pattern images (14) and machine position data (17) to parts that are members of a part geometry relation (15), and under part displacement constraints (16), finding given part positions or displacements (18).

Abstract: An apparatus and a method are presented for finding positional relationships and geometrical changes of at least one rotating part attached to or forming part of a machine when the part is in a rotating mode. In the apparatus and method, geometrical changes of the part caused by its state of production and use, determine any locations on the rotating part which exhibit contaminants, and subsequently remove or compensate effects of such contaminants present on the rotating part.

Abstract: A method and an apparatus for dimensional measuring of objects of any form and depth. The apparatus comprises at least an illumination system (1) having an optical filter (4), a manipulator unit (5, 6), and an observation system having an optical filter (9). The optical filters (4, 9) are designed so that most of the light passing the object and not being influenced by the object is stopped. The manipulator unit is such that between measurements either the object is made to rotate about one or more fixed rotation centers or to follow one or more known rotation paths, or the whole or parts of the observation optics are made to carry out a coupled movement or alteration in accordance with the whole or parts of the illumination optics, such that the illumination means and the observation means are completely or partly locked together and are altered relative to the object.

Abstract: An apparatus (5) for measuring the dimensions of an object (1) where a measuring carriage (6) moves the object at a distance thereabove. A polygonal mirror unit (32) receives laser light (16) and reflects it in a fan-shaped form toward a stationary angled mirror unit (37, 38) which directs the light towards a double-curved stationary mirror unit (39) which reflects the beam onto the object. Mirrors (40) of the polygonal unit are adjustable.

Abstract: A device for joining light waves by interferometric focusing optics and a small reflector with a cylindrical or spherical surface, which is positioned in the aperture of the object imaging optics so that the reference wave is reflected towards the picture detector and covers this. An auxiliary device comprising one or more reflecting surfaces may be positioned in the path of the beam behind the reflector so that the reference wave can be coarsely adjusted toward the reflector. In the extension of the path of the reference wave from the mirror via the lens to the reflector, a viewing screen may be positioned such that one by means of the naked eye can do coarse adjustment of the reference wave which focuses on the reflector.

Abstract: A method and a device for measuring and mapping vibrations wherein one or a number of local sensors and a measuring means can make local registrations and frequency decompositions of the vibrations of an oscillating object. The same sensors and measuring means may be used in combination with an image-forming unit and an associated measuring means for local and image-forming recording of the vibrations of an oscillating object, respectively. By oscillating an excitation source an object can be made to oscillate harmonically. Furthermore, the local and image-forming measurements are collocated with the aid of a means for calculation.
