摘要： A 3-D camera and a method for recording surface structures on an object of interest by triangulation, in particular for dental purposes. The camera provides for producing a group of light beams in order to illuminate the object of interest via a projection optical path, an image sensor for receiving light back-scattered by the object of interest via an observation optical path, and provides, in the projection optical path, for producing a pattern projected onto the object of interest. To avoid ambiguities in the event of large height differences, the camera provides for the projection optical path and/or the observation optical path for altering the triangulation angle, which is defined by the angle between the centroid beam of the projection optical path and the centroid beam of the observation optical path. The proposed process involves the taking of at least two 3-D measurements of the same object of interest with different triangulation angles.

摘要： A dental x-ray diagnostics installation for producing panorama tomograms of the jaw of a patient has a radiation source and a detector, which converts x-radiation into corresponding light radiation, disposed on opposite sides of the patient. The detector is preceded by a secondary diaphragm. The radiation source, the detector and the secondary diaphragm are rotated around the patient so that radiation attenuated by the jaw, and passing through the secondary diaphragm is incident on the detector. At least one CCD sensor is provided on which light radiation generated by the detector is incident. The CCD sensor converts the light radiation into electrical signals. The sensor has an image zone with a number of lines parallel to a longitudinal extent of the opening of the secondary diaphragm, and has a storage zone. The lines in combination receive all of the light radiation so as to generate a complete charge image corresponding to the x-radiation incident on the detector. A clock generator is provided which controls transfer of the charge from the lines of the image zone into the storage zone, and also controls read-out of the storage zone. By selecting the frequency of the clock pulses generated by the clock pulse generator, the transfer and read-out speed can be selected to simulate the speed of movement of x-ray film in a conventional dental panorama tomography apparatus.

摘要： A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object.
