    摘要: A process is disclosed for determining the vibration characteristics of a body by modal analysis. The body is made to vibrate at different frequencies and optical interference images of the body are recorded for the different frequencies. The interference images are analyzed on the basis of a mathematical/physical model, in view of the vibration characteristics at predetermined points, and the thus obtained information about the vibration characteristics of said points is subjected to a modal analysis.

    摘要: An apparatus is used for ascertaining the absolute coordinates of an object (1). Said apparatus includes a light source (6), projection optics, in particular a projection objective (7), a projection grating (2) which is projected onto the object (1) through the projection optics (7) to form an image, a sensor (5) for receiving the light (4) reflected from the object (1), and an objective (8) projecting the light (4) reflected from the object (1) onto the sensor (5). In order to enable the simple determination of the absolute coordinates of the object (1), the projection grating (2) and/or the sensor (5) are rotatable. There is provided an evaluation unit which evaluates the signals (shots or pictures) of the sensor (5) at least two different angle positions of the projection grating (2) or of the sensor (5) and determines the absolute coordinates of the object (1) therefrom.

    摘要: The invention serves for the contour measurement and/or deformation measurement of an object, particularly a tire or a structural component of a composite material. The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light. The light reflected by the object is picked up by a camera with an imaging sensor. In order to improve the image quality, a first image is produced with a first adjustment of the camera and/or the radiation source which is adapted to a first image region (13). In addition, a second image is produced with a second adjustment of the camera and/or the radiation source which is adapted to a second image region (12). Both images are combined (FIG. 5).

    摘要: A method serves the direct phase-angle measurement of radiation, in particular of light radiation which is reflected from a body. The body is exposed to coherent radiation. The radiation reflected from the body is imaged by an imaging optical system (6) in an image plane in which a sensor is located. A reference radiation generated in accordance with the shearing method is superimposed on the sensor. The phase of the radiation from the body is determined from the measurement signals of the sensor. To improve such a method, the imaging optical system (6) possesses a diaphragm (11) having one or two apertures (12, 13) (FIG. 2a).

    摘要: A procedure serves for the testing of tires by means of a testing system. The testing system includes a memory in which geometric data (1, 2, 3, 4, 5, 6) of the tire (7) are stored, and at least one probe (8) for testing the tire (7) surface. To improve on such a device, the probe or probes (8) are positioned with due consideration for the geometric data (1-6) of the tire (7) for the testing of the tire (7) surface (FIG. 1).

    摘要: In a process of making artificial teeth horizontal or other contour lines are generated on the ground tooth stump and on adjacent surfaces, said lines are detected by optoelectronic means, the data which have thus been acquired are used to compute the three-dimensional shapes of the tooth stump and of the required artificial tooth, and an artificial tooth having the shape which has thus been determined is then made by processes known per se.

    摘要: A method and apparatus for nondestructive testing of articles by holography in which light beams from a virtual point source of laser light and from an observation point are reflected by a reflector toward the same point on the object being checked. The light beams when extended beyond the reflector intersect on an ellipsoid having the point source and the observation point as foci. A plate having a hologram of the article is interposed between the observation point and the reflector and flaws in the object being tested show up on the plate as interference lines when the object is modified in shape by a mass influence such as a temperature change, or a change in pressure thereon, or by vibrations.
