  • Patent number: 9025164
    Abstract: The invention relates to a method for ascertaining material characteristics of an object, in particular optical properties of preferably semi-transparent objects. The aim of the invention is to obtain material characteristics without complex measuring methods. This is achieved in that spectrally resolved data from measured data of the object are calculated with spectrally resolved data of a reference body in order to ascertain the material characteristics, the measured data being ascertained with a confocal 3D measuring system.

  • Patent number: 8515528
    Abstract: A measuring arrangement and a method for the three-dimensional measurement of at least part of an object includes a light source with a continuous spectrum, a device for generating a multifocal lighting pattern, a lens with a large chromatic aberration for imaging foci of the lighting pattern on the object, a detection unit for generating the wavelength spectrum of the foci that are confocally imaged on the object via the lens, and a spectrum-dispersive device disposed between the confocally imaged foci and the detection device. In order to create a highly accurate surface profile in a relatively short time even in the case of moving objects, the invention proposes that a first hole pattern including first holes be disposed in the plane of the confocally imaged foci, the geometric arrangement of the first holes corresponding to the geometric arrangement of the foci of the multifocal lighting pattern.

  • Patent number: 8477320
    Abstract: Method for measuring the shape of a section of a semi-transparent object such as one section of a tooth, using a light source for generating light with a broadband spectrum in a device for generating a multifocal illumination pattern, a lens with a large chromatic aberration for imaging foci of the illumination pattern onto the object, and a detection device for determining the wavelength spectra of the foci confocally imaged onto the object via the lens, wherein a spectral peak position of each focus is determined from the respective wavelength spectrum, from which position the extent of the object in the direction of the imaging beam (Z coordinate) is calculated.

  • Publication number: 20130157212
    Abstract: The invention relates to a method for reversibly securing an attachment part to a base part by means of a connecting means which rigidly connects these parts to each other. For this purpose, an adhesive separating material is disposed between the base part and the attachment part, said material losing its adhesive effect reversibly or irreversibly under the effect of electromagnetic radiation.

  • Patent number: 6514278
    Abstract: The invention relates to a method and a device for the superficial heating of tissue by means of a pulsed light source. According to the invention a series of light pulses is applied to the tissue surface. The first part of this series is configured such that the tissue surface and, by heat conduction, tissue areas situated below the tissue surface are rapidly heated to a defined target temperature without tissue removal. The subsequent part of the series results in oscillation of the temperature of the tissue areas located below the tissue surface around a value which is slightly lower than the target temperature.

  • Publication number: 20010001818
    Abstract: A pulsed light source for cutting away biological tissue has a control unit that controls the light source in such a way that the light source supplies a series of pulses of predetermined duration and radiation intensity. The control unit may be operated to cause the light source to supply short pulses (10) at a predetermined and/or controllable rate of repetition with a radiation intensity sufficient to cut away the tissues, and radiation followed by light emission (11) or the like with a radiation intensity that is not sufficient to cut away the tissues but is sufficient to generate heat.

  • Patent number: 6186780
    Abstract: Method and device for the recognition of caries, plaque, concretions or bacterial infections on teeth, whereby with the aid of a light source (1) an excitation radiation (9) is generated which is directed at a tooth (4) to be investigated and there brings about a fluorescence radiation (10). The fluorescence radiation is detected and evaluated with a detection device (8). A spectral filter is arranged before the detection device (8) which restricts the fluorescence radiation detected and evaluated by the detection device (8) to wavelengths greater than ca. 800 nm, in order to make possible an improved detection of carious tooth regions. Advantageously, the irradiation of the tooth to be investigated is effected with a relatively long wavelength excitation radiation (9), the wavelength of which may be for example ca. 780 nm.

  • Patent number: 5306144
    Abstract: A device for detecting dental caries has an illumination device which emits radiation of a pre-determined wavelength towards a tooth. A filter accepts radiation returned by the tooth in a pre-determined spectral range. The accepted radiation is evaluated for caries detection. The illumination device has at least one light guide, by means of which the radiation can be supplied to the tooth. The illumination device emits radiation in the spectral range from 360 to 580 nm. The filter accepts the returned radiation in the spectral range above 620 nm. The device can be used in a flexible manner and enables a low level of caries to be identified.
