Abstract: In an improved method for the representation of the surface of an object, the actual 3D data (7) of the surface of the object are determined. The desired 3D data of the surface of the object are modified on the basis of the actual 3D data (7) of the surface of the object. The desired 3D data (5) of the surface of the object and the modified desired 3D data (5) of the surface of the object are used as the 3D representation data (FIG. 2).

Abstract: A head band for diagnostic instruments comprising a light source and a battery has, at its back support part (12), a flat housing (21) for adjusting and fixing the head band length by means of a rotary knob (22). An accumulator module (31) optimized with regard to volume, weight and weight distribution can be mounted and detached by means of bayonet-type grooves (25) at the housing (21) and pins (33) at the accumulator module (31), and can be fixed by means of a resilient spring (26) at the housing (21) and a recess (34) in the accumulator module (31) without impairing the function of the rotary knob (22).

Abstract: A method serves for the determination of the 3D coordinates of an object (1). An improved method of this kind is characterized in that the object (1) is surrounded by a plurality of reference probes (2, 3, 4, 5, 6) having coded reference marks (7, 8); and in that a plurality of shorts (10) are taken of the object (1) such that a part of the object (1) and a part of a reference probe (2, 3) is in each case included thereon.

Abstract: In a method for detecting the deformation of objects (1), a sequence of pictures of the object (1) is taken with a measurement method during the deformation of the object (1). From the pictures, phase images are determined. To improve such method, there is formed the difference between the current phase image or the respective current phase image and the phase image of an initial state. This difference or these differences is/are evaluated and/or displayed on a visual display unit and/or stored.

Abstract: A power source device for diagnostic instruments is adapted for a connection of different types of illuminating devices and includes an active control unit for controlling an operating state of a power source in dependence on a type of a connected one of the illuminating devices.

Abstract: A loupe support system includes a frame (12) which can be mounted at the head of a user and at which a holding device (18) is mounted, an elongated support element (30, 31, 68) which, at its central region, is supported at the holding device (18) such that it can rotate about its longitudinal central axis, wherein a respective loupe ocular (34) is mounted at the support element (30, 31, 68) on each of both sides of the holding device, and a light mounting element (22) supported at the holding device (18) such that it can rotate about a rotary axis being coaxial with respect to the longitudinal central axis of the support element (30, 31, 68).

Abstract: A tire testing facility used for testing tires includes a tire testing device with one or more testing heads (5) for testing the inner running surface (8) of the tire (1) and one or more testing heads (6, 7) for testing the outer sidewall (3, 2) side wall of the tire (1).

Abstract: A scanner is used for scanning an object, in particular one or more teeth (13, 14, 15) or a dental cast. An improved scanner comprises a carrier (2) on which a plurality of projectors (4) for projecting a pattern onto the object and a plurality of cameras (5) for recording the object are provided one beside the other in an array.

Abstract: A camera comprises a line sensor or an areal sensor (1) and an optical imaging system (2) for the projection of an image onto the sensor (1). To increase the resolution, a displacement device (6) is provided for the displacement of the image relative to the sensor (1) (FIG. 2).

Abstract: The present invention relates to a method and a device for determining the spatial position of a sensor, in which a rough position information initially is determined by rough detection of the position of the sensor, and then the more accurate position of the sensor is obtained by measuring at least three reflectors mounted on the sensor with a laser tracker, wherein the search region of the laser of the laser tracker is limited for the reflectors with reference to the rough position information.

Abstract: A method serves for the determination of the 3D coordinates of an object (2). A fringe pattern is projected onto the object (2) in the method. The light reflected by the object (2) is recorded and evaluated. To improve such a method, the fringe pattern is projected onto the object (2) by an imaging element (only FIGURE).
